depression
"I started off on the Wellbutrin 150 mg XL twice a day and I was exhausted everyday, not to mention the nausea was so bad I had to stop taking it. Just started on Wellbutrin immediate release at 100 mg once a day and it is a complete difference. I have so much more energy and focus, so far I love it. I do get a little headache by the end of the day but its not a big deal."
