I quit smoking 100 times in my lifetime. I finally reached a point where I KNEW I needed to stop - so - I quit by using the 'Patch'. Back then, when they first came out, you had to get them by prescription - but - now - you can get them over the counter. It will not do it ALL - he must do HIS part, too. It just takes the craving away. There was a series of (3) stages - at that time. You applied a new patch each day for 2 weeks that has 21 mg of nicotine in it. The next two weeks, you go to the next stage - a daily patch that puts 14 mg of nicotine in your system. The final 2 weeks, you apply a patch daily containing 7 mg of nicotine. It gradually weans you off nicotine. You cannot smoke while wearing the patch or you will overdose on nicotine. If he can make it thru that 6 weeks - he can probably make it all the way. But - he MUST make a commitment to HIMSELF to stop. All your talking, begging, yelling, preaching & pleading won't do any good until he admits to himself he has a problem & is ready to deal with it.
