Luna bars~I don't favor the chocolate ones, they just feel too sweet. I like the more "savory" flavors, citrus, orange, green tea....on longer rides the Cliff bar chocolate mint is my "secret weapon", just enough caffeine to kick in and get me going.

But you're right, seems I don't crave sweets. I'll have coffee with chocolate soy milk or chocolate almond milk in the morning but I don't crave it much. I don't know if it's age realted or just that I'm tryng to do less simple carbs.

As for "mind altering substances" I never could handle alchohol, 1/4th of a glass of wine and I have a buzz. So I don't drink.
