I'm going to throw the wrappers in the same garbage bag every time. Namely, my bedroom garbage bag, because I don't empty it out everyday.
This way, every time I go to throw away a wrapper, I'll be reminded of the 40 I've already eaten, feel a huge amount of guilt and self-disgust, finish off the one I've already opened (I don't want to be wasteful) and then not eat another until I've forgotten the aforementioned.
Whew. Gonna be a lot of work. Better start off with a cremesicle.
