Hello, congradulations on defeating your downfall! The Crystal Light issue should be based on how you feel about artificial sweeteners. If you are following the KT protocal, then he says "no sweeteners of any kind" should be used. I would be afraid to use it on phase 2, but it may be okay on phase 3. I have never had liposuction, but I do know that it can remove fat not excess skin. People that go the surgical route would probably opt for a tummy tuck to remove excess skin. Liposuction would remove some of their fat, but would most likely leave even more loose skin. Good luck on the rest of your goals!
