Everything I tried looking up only talked about quitting soda or how bad soda is for you etc.

I drink diet Pepsi [I'm not trying to quit drinking diet soda], it's the only soda I seem to like these days, I also drink either low-carb monster or Zero Nos energy drinks. But I don't have cravings for energy drinks the way I do with Diet Pepsi. I know some people say it makes you crave sugar etc. but I don't crave sugar, I crave diet Pepsi.

My point, is when I don't have it, before I can get to the store and buy more. How do I handle it, sometimes the cravings are very strong other times I can care less, it's not just the caffeine, it's the soda itself.

And don't worry about the aspartame part, I've read more about aspartame than most people. I know exactly what it is and I support aspartame completely.
