If you're like me, you really don't drink carbonated beverages (I make exceptions for the ultimate one, rootbeer). Anyway, I agree with bascially everything my esteemed Absorbentishe says in this with the exception of coffee. Not only do I think coffee tastes gross, it's a diuretic.

However, as a list in case you didn't read the quote:

Powerade, Gatorade, fruit juices (little bit more expensive but much tastier), lemonade, Lipton brisk type stuff (it's tea, I know, but it's a little different because it's canned), koolade, and milk

If you want a tasty, filling, nutritious drink, peel two oranges and put them in the frezer until they're half-frozen. Then, put the oranges in a blender with three peeled bananas. Blend and add orange juice until you reach your preferred consistency.

You can change it up with some pineapple juice, grapefruit slices, pieces of kiwi, strawberries, raspberries, just about any kind of fruit. It's an infinitely variable blended fruit beverage limited only by your imagination and the capacity of your blender.

SNAPPLE SNAPPLE SNAPPLE

Im a huge snapple juice fan and they are really good and have something for everyone. I particularly like the flavors snapple apple (tastes like youre eating an apple), peach raspberry, summer peach and super sour lemonade. Although its probably just as bad for you as soda, it doesnt have the caffeine.

Juices are wonderful...there is a huge variety (people seem to make juice out of everything these days). I particularly like grapefruit juices and punches. Water is really good, too...and it's free, since I like to simply store some tap water in the fridge so it's chilled when I drink it.

I, too, can easily down lots of Coke, but for the sake of my health I try to avoid it.

I quit drinking softdrinks 5 years ago... The first 3 months or so sucked.. but after that it was easy to say "no thanks, ill just have a water." The main thing was letting people know that you are avoiding softdrinks.

The only thing I drink now is orange juice, grapefruit juice(sometimes I mix those together... yumm) water... and beer.

A while ago I stopped drinking sodas for the most part, and then after a bit, on the occasion that I did drink one, I would get a headache right away. Not just Cokes either, anything carbonated. So now I drink water, Propel waters, Gatorade/Powerade, cranberry and grape juice and lemonade. And coffee. And tea.

Re: soft drink replacements?
 

the one thing common in pop and sweet tea is the high sugar content. For your taste buds, I recommend juice. Pineapple, orange, grapefriut, grape.... really any kind of natural fruit juice. V8's fruit juice is pretty good, and gatorade's a good substitute for pop. I started loosing weight when I stopped drinking pop after college.

I was addicted to diet soda dn drank it heavily. I found out I had aspertame poisoning and had to switch to diet rite. But I have slowed down and drink water, juices (not much..too sugary) and love Propell water made by gatorade.

For me when I quite soda it was and still is brewed Ice Tea unsweet. Not suger all the cafeen.

That and a lot of watter.

Milk, the complete meal (except it has no iron) + eggs for breakfast(lots of iron)
i have dinner after this

I'm trying to cut out all my soda drinks as well, I second the Brita plug above. Also, I would like to comment that a friend of mine drank nothing but sports drinks for a year and a half, ended up with bizarre gastro-intestinal problems.
point of the story: variety, a little of something is good, a lot is usually not so good.

Fruit juice is my favorite alternative to soda.
