Starbucks on the Weekend?

I am on Day 2 of no Starbucks. I'm resolving to only have Starbucks on Saturday and Sunday. How can I do this? I don't know myself. This is like saying "I'll just snort coke on the weekends, I can handle it." Really, I probably can't. I'm trying though. I need to do this. Let's just say if they ever come out with a study that says something like "insane levels of caffeine intake lead to inexplicable, sudden death after prolonged exposure", I'll already be dead.
