STOP with the Diet Coke!!

Everyday I wake up saying "I WILL not drink Diet Coke today" and then it gets to about 7:00pm and I just think fuck it, I'm tired, I've been studying all day, I've got however many hours left to hit the books, I need caffiene!!!  I'm weak willed to the point of silly. 

I've managed to cut down to one can a day (this is good for me!) but still, I'd rather cut it out completely.  It makes me feel bloated, it's not great for your teeth, etc.  I managed to cut out all fruit drinks so why isn't it working with the coke??

I love tea to death but sometimes you just want a cold drink, right?  And after chugging water all day...just no.  Stupid excuses.  Try harder Datura.
