I had a can of Mtn Dew with breakfast (I don't drink coffee, so I always have a pop first thing in the morning), and now I'm having another one at lunch. I usually have one in between breakfast and lunch, but I drank water instead, so I consider this to be an improvement, lol. I'm going to try to only have one with dinner and then drink water after that. If I can limit myself to one can with each meal, that's still three cans a day, but it's not a friggin 2-liter a day like I was doing before. If that works, I'll try skipping the can at lunch, too. We'll see how it goes. You never realized how hooked on something you are until you try to quit.
I was drinking upwards of 8 cans of coke a day for a while my senior year of college (by which I mean earlier this year). Took a weekend and went cold turkey. I was unemployed at the time, and decided to just tough it out. Holy crap. I was falling asleep and not realizing it, splitting headaches, shakes. It was awful. If quitting smoking is worse than quitting soda, I have major props for anyone who has done the latter. Anyways, I drink soda now, but much much less than I sued to.
