I havent been on Vissane, but I was on a very similar medication called orilissa for the last year, and can totally understand what you are going through. When the medication starts entering your bloodstream and making your body think and start to act like it is going into menopause it is very uncomfortable and painful (in my experience). I just went off the orillisa last week and my doctor told me it is a trade off - those strong medicines are really great for stopping tissue growth and have some strong side effects. I will say I became more used to the side effects over time and three months in started feeling them less. I hope you feel better soon and know you are not alone!!!!! 💛
