For what reasons might wellbutrin (bupropion) seem to make my hands shake and my veins in my hands stick out?

Wellbutrin (bupropion): Wellbutrin (bupropion) is a more activating antidepressant than some others -- in some people, it can lead to shaky hands, etc. Please speak with your doctor about your concerns; adjustments or changes may be possible.

Caffeiene?: Regarding shaking hands- how much caffeine do you drink? I don't start patients who have high caffeine intake on wellbutrin (bupropion) until they have tapered down. It is an awesome medication except when mixed with caffeine.
