Nervous anxiety symptoms and conditions

Have been on Cymbalta 30mg daily for a year. Started on Wellbutrin 50mg daily about 6 weeks ago to help with attention deficit. About 4 weeks or so ago I started having occasional muscle cramping in hands and feet. Yesterday I started with twitching of left eye. Last time I had the eye twitching it was the beginning of an allergic reaction to Prozac. I'm thinking even the low dose Wellbutrin may be too much. anyone else had this experience? I'm also starting to notice an increase in anxiety. Not sure if it's due to worrying about the cramping and twitching or the Wellbutrin itself. Any thoughts?
