As someone who likes a smoke (Weed & Cigarettes) and is currently trying to lead a healthier life I feel your pain buddy!

Have you ever tried just cutting down? Even just a little bit? I don't believe in this "Just stop and never drink again" rubbish I think it has to be done in baby steps.

Anyway, hope you're okay and whatever you do don't go the religion route. It's a dangerous path to tread especially with the types who run these things.
