I've never been a big pop drinker, but do subscribe to the "everything in moderation" way of life! I have been the same weight since high school 188-195lb, and if I do happen to have a pop because it's the only thing spitting out of the fountain machine, it takes me about 3 days to drink a 16oz cup!! Yes, I'll still drink it after 3 days, cause I'm cheap and it costs me money! I drink Arizona Ice Tea most of the time, and drink about 1/2' of the can and fill it back up with water! That system will also last me about 3 days, I buy one every Wednesday for practice, still have some in the can this morning!!
I don't rely on will power, I just don't do it if I don't want to!! The others on my crew will buy a 24oz cup, drink the whole thing and refill it to go!! I simply can't drink that much liquid no matter what it is!! I don't care how good or bad something is for you, if you listen to everything you read or hear, you'll never leave the closet!! You know your body better than anybody, do what's best for you!!!
