used to smoke regularly but i now am QUITE successful at being a social smoker (though at the same time there's nothing like a bad day at work to drag you back into the soothing embrace of nicotine!)
If i could i'd smoke regularly. I enjoy it, so fuck the long term effects! Only problem is the old asthma means the long term effects are reduced to quite present effects. After a few bad bouts of chest problems, and one particularly bad moment, i've reduced the amount i smoke... as the unpleasant choking etc was overshadowing the pleasantness of smoking.
But i can't see myself ever fully quitting. It's enjoyable, i enjoy smoking when i'm out, and i live to enjoy life!
But kudos on quitting! It's not easy. incidentally, don't you hate when non smokers tell you to quit? the old 'how hard can it be' crap.... quite hard!
