It is soo hard just drinking water .. how bad would it be to add crystal light once in a while for flavor.. i hate those flavored waters but love lemonade crystal light
Baaaaad. Seriously it will just make you crave more apart from the damage it does to the fast and your body. Try carbonated water, it doesn't taste any different but some say it helps. Or warm water.
You might want to check into the Aspartame forum. Dumping more formaldehyde and formic acid into your body while it's trying to get rid of it is not a good idea. At some point you may want to stop drinking it permanently (sooner the better).
Try different mineral/spring waters. You might find something a little more to your liking.
