I don't think water is dangerous if you do it properly and add sugars and salts and maybe alternate glasses of water with gatorade or similar.

Plus it's cheap and easily available. You gotta hold on way longer than 1 pot of tea before you pee though, to see results! Don't try and drink too fast. If you get dizzy, slow down. Avoid drinking cold drinks (go for room temp or lukewarm) or you'll chill your insides down too much and start shivering from the inside out, which is unpleasant. So I guess tea is good for avoiding that (that's on the assumption you meant warm tea made from an infusion as opposed to iced tea?).
Have fun
