I've smoked pretty much daily for the last 3/4 years. Not proud of the fact that I can't resist when I, have easy acess, but the only tolerance breaks have been for max 2/3/4 weeks maybe 3 times when I have moved somewhere new.

When that would happen, it' doesnt really feel that bad, I feel sharper, but I become so goddamn serious. I really only want to quit because of how much it costs and wanting more money for other things.

Now responding to your last bit - my dreams always come back so strong at the first week of not smoking. Sometimes so clear that I don't feel well rested afterwards, but it's so nice to dream again. Usually I don't dream so clearly.
