Yes, I’ve had the same effect, even now that’s I’m on 1 tablet of proviron every 12 hours. All seemed well and loose there for a few days, and all has tightened up again. I’ll add that for the first few days of taking a half a tablet a day, I woke with really strong morning wood, than had 2 bad days (food, schedule, stress) and no wood. After increasing to a full tablet, the wood has been back and consistent, but not as strong.
Additionally, I’m feeling slightly more irritable (or frustrated/angry) and don’t know if the proviron is related or not, otherwise my mood has been a little bit better, and I’ve even started running again, which is something I haven’t done in years.
I’m also sometimes seeing veins appear again on the tops of my hands. They “disappeared” under what has become tight, wrinkly skin for the last few years.
