"i was on citalopram 20mg and due to a death in the family, i was unable to get my prescription renewed before i ran out. so two months passed before i got to my doctor and i had done extensive research before making the decision to switch to bupropion. i have been on it for 4 days now, and i definitely have the get-up-and-go that i never had before. i am beginning to enjoy the things i used to again.  however, i am a serious coffee and sweet tea addict and for the first 3 days of use i had diarrhea and according to other people&#039;s reviews, it&#039;s actually quite common. i also was concerned because falling asleep is just a little more difficult but i still get 8 hours. i guess i&#039;m still adjusting to the idea of being normal and stable."
