Being a regular smoker seems to require regular breaks or your tolerance is going to blow through your budget and you won't even have the advantage of being high while all your money disappears. A week or two off does wonders. A few months off and that first day back is really nice. I've never been very good at regulating my dosages. I find it much easier to switch between consuming all I want / not consuming anything at all than trying to maintain a consistent low dosage.
