I suppose my earlier introduction wasn't sufficient. Hi there—normally I just read along, and I only chime in when I've got something worth contributing.
A thread about Cialis (tadalafil) caught my eye, so I wanted to share my experience: for roughly a couple of years, I took the maximum 20mg dose, once every three days. At my most recent appointment, my doctor picked up on heart palpitations and had me use a Zio patch (heart monitor) for four days. I experienced a lot of palpitations, among them double and tripple, and on many occasions my heart didn't pump correctly three times in a row.
Because of that, I quit taking it, and within about four days they became less frequent. It's now been more than a week, and I believe my heart rythm is back to normal. I plan to ask the doctor for a retest before long.
