I am pretty much the same way. I finally get some extra cash around and hopefully find a good dealer who actually gives me a good product, during which I have a lot of fun, and I always promise myself to take it easy and conserve it throughout the month, or stuff like only use on weekends or just a bit each day, but it always ends up me smoking more and more until I run out and then go buy more and repeat till I either run out of money or crash, to which I am too tired or anxious or paranoid to approach one of my dealers. Usually it is a once a month ordeal that lasts 4-5 days. Used to do that then be miserable for a few weeks till I got next paycheck, or would counter with alcohol and smokes for withdrawal, but now I have mastered it where I save prescription drugs like Dexedrine and Xanax for the comedowns, not to mention stocking the fridge of food and getting everything done before the binge starts, cuz it just is pretty much impossible to end it until you run out or pass out, it is just too much fun and chain-addicting, like chain smoking or eating a bunch of junk food I guess.
