"i just started prozac again after being off it for several years.  after going off prozac the first time, i tried battling depression with alternative methods, including yoga, exercise and cbt.  recently i decided i was losing the battle using these methods alone and went back to prozac.  my experience so far is that the medication is working. i have so far not been experiencing the really deep lows while on this medication.  i do feel a bit drowsier that usual, although this is not entirely unwelcome as i was having trouble sleeping before and now i find i am able to sleep and nap more easily.  exercise and avoiding alcohol dramatically helps with the drowsiness issue and also helps improve mood further in combination with the prozac."
