I've experienced this on both Effexor and Nardil. When the weather gets up to around 90 with high humidity, I begin seating A LOT. My shirt is soaked in sweat and my face is dripping sweat. Everyone makes comments about it and asks me if I'm alright. I take 60 mg of Nardil a night. I had to bring it down to 15 or zero and after a couple days the sweating dramatically subsided. However, I've had horrific nightmares and my feelings of sadness are starting to return. Has anyone been able to conquer this problem? Should I change when I take the Nardi? I also take glycopyrrolate to help stop the sweating, but it does little good.
