Experiencing the same issue, and it's worse during the night. There's a feeling that my prostate is more enlarged than it typically is. However, I ceased SS-31 usage several days back, following a cycle that lasted 1 month. My daily intake was 5 mg, following a 2-on, 1-off pattern.
Because this has continued and is rather bothersome, I've taken pumpkin seed extract along with some other things today; I'll check how I feel the next night.
For those who are still too young to grasp what this involves: it's unrelated to dehydration, and it isn't a urinary tract infection. Drinking excessive water in the evening is truly not a wise move.
