bupropion xl is an antidepressent, any one used it before?

I have been on Wellbutrin, or Bupropion successfully for the last 8 yrs or so. I take it with Cymbalta and the two seem to work well together. The first week is a little tough as I got a little jittery and felt "off". It did go away and I haven't had any problems since. I take 300 mg. Hope this helps!
