"i&#039;ve been taking citalopram 20mg everyday for 8 months now, i am 28.  this medicine makes my moods more stable but i get bouts of tiredness (which can be frustrating).  it now seems, when i normally would get angry/sad/frustrated, my mood slip is overcome by a tolerance. no highs or lows, it&#039;s like i shrug off what is bothering me.  other medicines would make me feel like a zombie but with citalopram, i feel like myself. i sleep normal now, concentrate as usual, socialize little more, understand others better, relax more, motivated more.  i got rid of that downward spiral i was headed for. i did notice best results early on in my prescription and it has lessened over time."
