Bupropion
smoking cessation
"Day 1 a bit of feeling "doped up."  Day 2 OK; nothing significant.  Day 3 the nausea started. Ciggies tasted horrible but even worse than that, just the thought of food and I all but headed to the john to throw up.  This was the three day one pill a day phase. Side effects of Chantix (including nausea) were not as severe as this.  I'm still waiting to see if after 24 hours that last dose will finally wear off.  Cold turkey, bad as it can be, is way better."
