Caffeine MOST DEFINITELY makes me hungry when I shouldn't be. It's been a struggle for me to give it up, too.... but I try like heck now to keep it under 250mg/day....that's 2 6-oz cups of coffee and one glass of iced tea. It really will be worth your while to make an effort to cut back. Besides, it's hard on your liver and bad for your digestive system....two pretty important organs when it comes to weight loss and health maintenance!!
