Last time I stopped drinking I waited three weeks before attempting to stop smoking. Eleven months later I picked up a drink then a few nights later started smoking again. Alcohol destroys my will power where nicotine is concerned.
I'm going to quit smoking again next week which gives me about a week to get over the initial hump of stopping drink. I know if worst comes to worst I'd pick up a cigarette rather than a drink and I'm ok with that. I'll give it a shot but no pressure.
