Insufficient Dosage of Startbucks Coffee!!!

I'm in a serious need of some coffee. Starbucks to be exact. It's been nearly two weeks since I had my last dosage. And today I really need one. Like RIGHT NOW!!! Someone save me!!!
So I'm in school right now on my 4 hour break. Started at 12. Before that I had a 4 hour lab which started at 8. Obviously I was late. Fell asleep just as I was about to leave the house. Actually wanted to go grab some Mac breakfast, but ended up having none. Thursday really sucks.
