I've been kicking my caffeine habit for years. At my worst, I was up to about 6 cups of coffee a day. Then I mostly quit coffee during the day, and switched to Mountain Dew. It was kinda weird, cus I don't like carbonated drinks, but I got over it. I think I mostly used the caffeine to avoid hunger. I don't eat breakfast or lunch.
I don't think I want to quit coffee all together, but I don't want a caffeine addiction anymore, and I really want to stay way from soda.
It's just plain hot water. I think I drink it cus I am in a cold computer lab most of the day. I'm a lab rat. I also don't get hungry if I keep drinking. Maybe I should just start to eat.
