For me no coffee=no go (or 'no va' in Spanish, like the car, the Nova, which didn't sell well in South America when it came out).
I drink more decaffeinated coffee than I used to, and have moved away from bling coffee at Starbuck's, since I'd rather pay for gas in my car so that it can 'va.'
High fructose corn syrup, the sweetener that's put into almost every sweetened drink, is what's toxic to me.
I like coffee.
