I’ve been taking 150 mg of bupropion XL for a little over a month now. I accidentally drank a cup of caffeinated coffee and about a half hour later my heart started racing and I couldn’t get it stop . I thought I was going to have to go to the hospital but after a about an hour and half it finally went back in rhythm. That was so scary and now I’m scared to death to drink anything with caffeine. Anyone else experience this ?
