I was taking 5 mg and started feeling much better for about 6 months. And then all of a sudden I started to get short of breath while walking or just going up one flight of stairs. As well as getting dizzy. I walk and bike daily and feel that I’m in good shape and I don’t understand why the symptoms started all of a sudden. I started taking this drug and thought I found one that was finally working, but stopped and can’t find anything to help with my depression and anxiety. I’ve tried them all!!
