... I started taking Wellbutrin 150mg twice a day to quit smoking. Day 3 of starting it I ate, took med & within 2 minutes I got chocked on my drink & threw up. I assumed that I had also puked up the pill,, so I took another one & omg within ab 2 hours I was speeding like a rat on acid & it lasted ALL DAY LONG & INTO THE NEXT DAY. I’m kinda scared to even take 2 a day now. On the good side I only smoked 4 cigs a day each day. What was happening to me??
