"this is my second time on wellbutrin xl. i took it once when i was 14-15 with no negative side effects and i&#039;m now 18. my doctor started me on 150mg and then bumped me up to 300mg and it helped so much. this time when i started, i got headaches for the first 10 days which were pretty bad sometimes but it was worth sticking them out (i had headaches during depression anyway). and for a period of 1-2 weeks i would wake up in the middle of the night for no reason but i could usually always go back to sleep. i have more energy and i don&#039;t dwell on things as much. overall, very satisfied."
