hi, i had the same problem with wellbutrin, but was otherwise very happy with its performance. i actually had less trouble with the wellbutrin xl, than with the wellbutrin sr. i found that if i take it in the morning that helps.

but what helped even more than that was when my doctor prescribed a small dosage of desyrel to take before bed every night. it's an antidepressant, with some sedative qualities. i take 12.5 mgs usually, 25 mgs if i'm having extra difficulty falling/staying asleep. it helps me to sleep more soundly, and usually i can wake up after 6-9 hours feeling a little groggy, but well-rested enough to get out of bed. this is a huge deal for me, as usually when i'm depressed i sleep for 15 hours at a time! i had tried ambien, and sonata, but the desyrel seems a lot less likely to cause long-term depressive symptoms (as it's an antidepressant).

good luck!
