Anyone one been on fluoxetine and not had any problems with weight gain before I went on them July 2012 I was a nice 9 half stone I'm now up to 13 stone and feeling awful? Would be good to know if sum ones had the same problem and had change of meds and what to. There good for anxiety and the depression but the weight gain is making me low in myself and having to clear my wardrobe out :o(
