I’ve been on Venlafaxine for years unfortunately and I sweat all day every day to the point it makes me thoroughly miserable at times. I’ve been told by my pharmacist who does my yearly medication review that it could be due to the Venlafaxine, I hope to eventually come of off them. Also Gabapentin is for nerve damage which I have and also been offered them but refused due to the side effects that they can cause, Wet Macular Degeneration (blindness) my Mother & Grandmother both went blind due to Wet Mac so obviously I declined. I don’t understand why your GP is offering you quite heavy meds that are difficult to get of off for your sweats, personally if I were in your shoes I’d go down the more natural route first. Is your GP a woman? Have you got a menopause clinic near where you live?
