Paroxetine
"I took Celexa a few years back for my chronic depression.  It didn't make me feel so good so after 6 months I went off it, cold turkey, and dealt with the withdrawal symptoms of that drug (zaps!).  So when I got offered Paxil for my social anxiety and depression, and heard that there were withdrawal symptoms, I decided that if it helped, I'd try it.  In just these few weeks, my friends and I have noticed a huge change.  No weight gain, more energy, upbeat and outgoing, smiley and laughing, and optimistic for the first time in...my life?  Only downfall I've noticed so far is the crippling nausea and dizziness the first three days of taking the medicine. I feel fantastic now!"
