Crystal light bad?
If I remember correctly, the reason people were not drinking crystal light is that they did not care for the taste. My nutritionist had told me that Crystal light is a fine drink for us post RNY. I have found flavors I like and some that I don't care for. Like Bama noted, I also make Ice Tea and add some lemon and Splenda, which I prefer over the Crystal Light teas.
I think the secret is finding what 0 calorie or very low calorie fluids that you like so you can get your 2 plus liters of fluid in each day.

Crystal Light often has Aspartame as a sweatner.
There is a lot of debate about aspartame - most people without a financial insentive agree that it is or can be an appetite stimulant.
For me that is very very true. So I have to avoid it.
Do not take liquids after meals for 60 minutes or whatever your doctor says.
Liquids should help you feel full and less hungry. If while or shortly after drinking crystal light you feel more hungry then you should stop.
Other than that I agree with the obove posters.
