I smoked cigarettes for 32 years, and I was an avid and often fierce smoker often going through 1+ packs a day. I retired from my career job and quit smoking cold turkey - BOOM- just like that... I was a miserable prick to everyone for a short time while I was jonesing for the nicotine and there are still some days that I feel that one more coffin nail would be SO GOODLY SATISFYING...
Point I am getting at is to just quit that shyte, seriously, quitting will not kill you, stopping will not ruin your health, stop making excuses. Friends might not hang with you while you are in that miserable prick stage of quitting, the goodly ones will stand by you though (unless you are really really pricky). Way better than the crap health alternatives (plus the added unreasonable expenses for you USA folks) of lung disease or mouth cancers.
Toughen up and throw that shyte into the trash.
