Hi Daz
I gave up the cigs 8 years ago, no pills, no patches, just will power. Not easy, I had smoked since 13 years old, stopped at 40 with no stops in between. When you feel like a cig, say to yourself I'll have one in 5 minutes, it never comes, you'll either be busy doing something else or have forgotten. Craving will come back in half hour or so, but just say to yourself 5 minutes again. Try it, you'll be surprised.
Still like a drink though, think that would be harder to give up completely.
Good luck.
John
