I gave up the fags 8/9 years ago.... I virtually went cold turkey. I tried the patches for a week or so but, in the patches box was a table of dates and stickers. One day without smoke - another sticker etc. I got obsessed with finishing the stickerboard!! I did it - something like 3 months...!! But I also saved every penny I would have smoked for ME, and ME alone....One Yamaha guitar, one Lowden guitar, one Stelling banjo, one Eastman mando, one Oakwood mando and one Collings mando later, I'm still off the fags, still save the money (usually in pound coins that I take to local store to exchange for big denomination notes.) Ok - I'm still feeding a major addiction (MAS/GAS)- but this one shouldn't kill me slowly and agonisingly..and mostly, it's not antisocial!! ;-) (Unless I play outside!!) Re. giving up the gum - no idea,apart from CT and willpower... but it's got to be better than smoke and shit..... Good luck..
