Looking back, what do you wish you'd known before starting a GLP-1?

What I could have done is start it earlier....and my insurance picked up the tab. Going by the marketing and info I was fed, it looked like something either celebs abused or something for ppl in super special circumstances who had already cycled through every med that didn't work.

The prior auth went in from my doc, came back approved the same day, and 24 hours after my doctor urged me — saying I qualified and it would drastically improve my life — I had my first pin. And it was Tirz not sema lol. Shout out to my doctor: they changed my mind, and taught me about glps, a complete 180 from what I've read online/read on the news.
 
Changing how I eat was something I had prepared for. That how I drink would need changing too — hydration, not alcohol — I had not realized.

Delayed gastric emptying has meant that I am

drinking less as well. Staying hydrated matters a great deal, not only for health but for warding off GI side effects.

So new hydration habits had to be built: sipping slowly, keeping a water bottle on me, and turning to flavored waters or diet sports drinks on the days my usual water or plain seltzer won't go down, etc.
 
The thing I wish someone had told me is how "normal" it would leave me feeling — presumably the way people without metabolic problems feel all along. Insurance won't pay for mine, and my doctor spent years steering me away from it, warning that the side effects were dreadful and that I'd be stuck on it for life. Despite my obesity he refused to even talk it over, so he is no longer my doctor. Side effects for me are close to nil, and the rare ones are so slight they barely register. Staying on it for the rest of my life suits me fine, because beyond the weight loss the way it makes me feel is worth far more than that.

Roughly two years back (before tirzepatide existed), a specialist I consult remarked along the lines of, “You know, all your issues are this weight [and made a big hand swooping motion]”. Years of appointments with him had gone by with it unspoken — the elephant in the room. I met his eye and the words came out of nowhere, “Well, I’m thinking about one of those glp1 medications.”. Back came, “YES, YES, YES. Just do it. Don’t think about it”. Within two months I was on tirzepatide.

For any doc who would talk an obese person out of trying medications like these, firing them and finding another is the best move. Good on you for getting rid of them!

This has come up for me before with my doctor…I asked her to write me a script for Tirz, and her answer was that compounded Tirz is sold right out of their office… 😳 …I left carrying 4 prefilled syringes of Tirz…👍

Thank you! He was awful, and once I dropped him every other provider I see has been fully behind me taking it. Wonderful that your doc backs you the same way! My theory is that doctors used to dodge the subject of our weight because no dependable treatment existed. That excuse is gone now, and there is no reason for them to stay so ignorant about it!

Now that is service! Prefilled syringes give me pause, though — a bit dicey. Unless what they handed over were the fancy glass ones from Medivant.

Back when I started, my pcp belonged to a practice where prescribing compounded tirz or sema is off limits 🤷🏻‍♂️ 🙄. He did say, though, that he would work with me if I chose the compounded route.

Going in, my assumption was that the weight would come off and then I would taper. That the drop in food noise would be this dramatic never crossed my mind. Loads of food noise was something I already knew about; picturing what quiet would feel like was beyond me. I also assumed giving up certain favorite foods was off the table, yet on Reta those foods mean nothing to me! They aren't missed. A reseller was my starting point, just to test whether I even liked Reta. Going grey 3 weeks later was not something I saw coming.

Book group meant I was the one bringing donuts this morning. Picking them up wasn't something I dreaded exactly, but I was curious -- would a couple extra end up in a personal stash? Would I go overboard? (Not something I've done since last Fall.) Donuts are such a binge-able food, and this shop is bomb. Welp, a bunch of them came home, got cut up, and were laid out real pretty on a platter. One was set aside for me: lemon filled. Nothing else called to me.

Once the meeting ended I was semi-eager to eat that secret donut of mine. Not voracious, just, um, well, okay, let's see. A bite of dough went in and -- meh. Not very delicious. Dry. Next came a bit of the lemon filling, and as I did it the picture that arrived -- unbidden -- was the industrial food sized can it had come out of. Nothing about any of it was tasty or appetizing.

It went in the trash.

A year back, the notion that I could eat a highly palatable food that slowly and with genuine curiosity was nowhere on the radar. Today there was no deprivation involved; I simply tested whether I actually wanted to eat the thing. Making that room to think about what's going in my mouth, rather than wolfing it down based on, idk, memories of how I assumed it would taste? For me that is the new and priceless part of GLP1.

None of how it worked had been explained to me…and when a reup was due, a note through the patient portal was all it took, and back came word to drop by any time for more $$$$… 👍
 
How much a set of blood work tests and a dexa scan would matter.

More than a year has passed since my last blood work, yet 3 months back I went into gray GLPs off my own bat. Official baseline data to check myself against each quarter is what I wish I had now. The same data would also show which other peptides are genuinely worth researching.
 
What I wish I had known is that a day would arrive when I could stand at the open fridge for a while and take nothing out to binge on.

Bonus point: walking without tears from the pain.

Same here — once 100+ lbs were gone, I got a dexa at 223, and I wish one had been done right at the beginning. It's never too late, though...

Blood work is something I get done constantly, so mine goes back to day one.
 
Much of what has been posted here matches my own thinking. A handful of other scattered things I wish I had known: the electrolyte dumping hit me harder than I anticipated. Long travel days for work, on top of perhaps under-eating and under-drinking because my body had lost its usual cues, produced some wild lightheaded spells. Once, at the park with my kid, I came close to blacking out purely from not having taken in enough fluids. Broadly speaking, once the natural reminders to eat and drink disappear, keeping ahead of it becomes essential.
 
Anhedonia is brutal.

Do take a daily supplement, since poor nutrition can leave your teeth suffering.

Cardio every day is non-negotiable.

Sleep will take up a lot of your time.

I'm not in that situation.
 
I wish someone had told me that even at a dose below the therapeutic level, I'd drop both fat and muscle, and that protein was essential! When I was at my highest weekly dose of 1.5mg of Reta, I shed pounds along with muscle mass I had no desire to part with.
 
Every GLP-related youtube video out there tells you to drink more water. A gallon or more per day is what some of them push for anyone on a GLP.

Straight water isn't something I drink, and my liquid intake has stayed exactly the same, not down by even one ounce. Started on March 6th, 2026 and the losses keep coming. One rat is the whole of my research, and I won't claim that makes it a proven fact. This is just me sharing a small piece of my research.

My schedule was already all over the place, but nothing could have gotten me ready for the way it slows every process in your body down to a stop.
