I am not recommending that anyone do this, but it worked for me as far as turning me off from cigarettes/nicotine when I initially quit roughly four months ago while constantly being around chain smokers on the property of a substance abuse treatment facility...I would double up on my bupropion and take 300mg twice daily(Never take this much in 24 hours-multiple reasons not to) because 300mg daily wasn't curbing my cravings, even though when I did smoke on Wellbutrin/bupropion, the nicotine hit was very diminished and it was more of an addiction to the ritual of inhaling and exhaling smoke and the whole hand/mouth thing as well as an excuse to go take my antisocial ass outside. I would make a point of also drinking excessive amounts of instant coffee. The combo of high dose bupropion and caffeine would make me very nauseated and hyper-stimulated and nervous and although I never puked (or had a seizure), I came very close to vomiting so smoking a cigarette was about as enticing as smelling fresh dog shit. Another thing that brought me to the brink of emesis was drinking down 6 to 8 bags worth of black tea. I had perphenazine as a safety net for an upset stomach so I'd put myself into a nauseated state when cigarette cravings kicked up. Not fun but it worked. An optomistic mindset is important for quitting-I've gotten off a long term cocaine habit, an even longer trainwreck opiate habit, and most recently a dextroamphetamine addiction that nearly killed me, so I knew that I was mentally capable to kick a chemical that doesn't even get me high. And if I'm gonna abstain from the euphoric garbage, why continue to stay hooked on something that will damage my physical health if not eventually kill me? Plus it was such a pointless waste of cash.
