I recently changed from sertraline (150mls) to venlafaxine due to a number of reasons- the main one being I was feeling flat and numb on the sertraline- I had been on it for 3 years and it pretty much kept my depression at bay. Venlafaxine was good to start with, no side effects, but 2 weeks in I couldn't stop eating, I couldn't sleep, if I did I was having awful dreams, shakes, constipated, nausea, the list was long! So went to the dr this last week and she has prescribed me with a different type of anti depressant- can't remember which one, begins with a F, away to pick it up from the chemist shortly- well hopefully. Stopped taking the Venlafaxine on Thursday- took my last one, ever since my I think I'm suffering from withdrawal?? It that possible on 75mls for 4 weeks? I feel dizzy and nauseous. My mood has detrioated rapidly in the last 48hrs- I could actually stay in my bed all day, crying, feeling angry, hurt the list is endless. This is the reason I've not been to pick up my new Meds. I can't leave the house. I haven't left the house all weekend. I feel hopeless, to the point I don't want to start taking the new Meds, what if they make me feel the same???
