You seem to have misunderstood the problem, which absolutely was caffeine, not sugar. I cut caffeine because I was using it as a crutch to get through the day, much like I did with alcohol when I was addicted to that. As of today, I've been a month with no caffeinated soda (only Sprite in the cherry limeade that the local wing place makes), no coffee, no tea. The only caffeine intake I have is via chocolate, which is extremely limited in nature. I will not "get used to" the flavor of coffee or tea, because both taste like distilled ass, and I won't drink them. For the life of me, I will never understand how people drink coffee. The bitterness you so love makes me nauseous. It smells delicious, and then you drink it and gag. That's not something I want to get used to drinking.
Yes, sugar is a problem, and I understand the repercussions thereof. We're working on cutting it down dramatically as well. We don't keep sweets in the apartment. No candy, baked goods, etc, unless it's a special occasion, and even then they are kept to a minimum. Most of my sugar intake comes from the occasional hot cocoa, because Wolfeyez spoils me and puts marshmallows in it.
Water does have a flavor, and I've finally found a bottled brand that I can stomach. Ice Mountain is not horrible, and I drink a good lot of water via bottle nowadays. There are some places that I can refill my bottles from the tap that aren't horrible, like the college drinking fountains, or my parents' house, but the tap at home is awful and Brita filters make it worse. Oddly, the Brita filtered water makes it taste more like plastic than the bottles do.
I've cut about 900 calories a day from my diet by ditching pop. I was anywhere from 1.5l to 3l every day. That maxes out at nearly 1400 calories, or almost a pound and a half of fast food alfredo pasta.
