depression
"I took wellbutrin to help with motivation and energy, which were major sources of my depression. The first two weeks were absolutely terrible. The only side effect I had was night sweating, and it was so bad that I got no sleep every night. I would fall asleep and wake up covered in so much sweat there would be pools of water on my chest. Had to wear clothes from head to toe and sleep on a towel. 

After that it worked fine. However, it didn't really help with the motivation. It gave me more energy, but didn't allow me to use it for anything. That ended up increasing my anxiety. However during this period I did not experience a single side effect other than occasional chest pain which was probably from the anxiety/stress anyways."
