If you plan to give up caffeine then you can't have Tea, Coffee, Cocoa, and some shampoos and soaps.
I gave up Ice Cream, I might end up being a type 2 diabetic in the future.
A tool is a tool regardless. I mean if you suck, you suck, and not even the most perfect tool could save you. And if your damn good then even with the worst tool ever conceived you could chug out some high quality shit.
