You can ween your way down to 0% nicotine cartridges, and then quit all together. It worked for me and it has been almost 3 years now.

I live in New Hampshire so brand name cigarettes are a little over six bucks at most places. I figured I was smoking a little less than ten packs a week. Well that's sixty five dollars that I could be spending on my kids. I decided I had to choose between killing myself by smoking or making my kids happy that we have money for fun stuff on the weekends. Kids win. My husband tried thinking this way but he just can't quit. Chantix made him mentally unstable and wellbutrin made him more anxious. It's hard to do but I feel so much healthier now. And I don't smell like an ashtray or have smokers breath. I have gained ten pounds though. That sucks. Gotta pick your battles I suppose. Good luck.

Thank yall
