Whats everyones opinion on this?

How bad is this stuff for you if you add it to every bottle of water you drink??

Individual food (or in this case drink) choices are personal decisions. If you like the stuff and it works for your diet, drink it.

What do you mean by "how bad" is this stuff for you? From what persepective, health or weight management?

Health -- I have no idea. Take a look at what's in it.

Weight -- isn't it one of those like nothing calorie mixes?

I'm pretty sure Crystal Light is sweetened with aspartame (nutrasweet). If you're worried about aspartame consumption, steer clear of it (or at least minimize it). If you're not, drink up. There's basically nothing else in there.

Some people consume gobs of aspartame with no apparent ill effects. Others swear it'll give you everything from cancer to erectile dysfunction. I steer clear of it because it seems to cause/encourage my vertigo. It's probably not actually even related, but it seems like it to me, so I avoid it. Whether you avoid it or not is really up to you. Read up on the aspartame literature if you're concerned. Try to get a balanced viewpoint, though. Don't just get your health information from nutjobs who swear aspartame is responsible for all of society's ills.

If there's no calories in the drink, I say drink up!
