Hi Tannie, I can understand your concern. that would scare me a bit as well.
I just wanted to say that I don't agree with the carnation instant breakfast....there are so many protien shakes out there that are better than that.
Although everyone handles them differently, and while I may love the flavor of one, someone else might not like it at all. It's just my opinion, since I am not a dr, but I would look for one that has more carbs, specifally sugar, to help you from getting those "light headed" feelings. You may have to drink more than 5 a day until your body adjusts to the diet....I was on just shakes for a week, then was able to have creamy soups, then the 3rd week was allowed to have soft fish.
My sister had problems her first week, so she was told to start eatting some thin, creamy mashed potatoes.
Just some ideas...but I wish you luck and hang in there you'll do great! Let us know!
later, Joanie :biggrin:)
