How can you tell if your protein shake is healthy?

Sounds to me like you might be lactose intolerant. If you are using whey protein see if it is whey isolate not concentrate (look in the ingredient list). If it already is isolate try switching to soy protein. Hope that helps.

I did check at the first ingrediant is Soy and I am so many medications where it messed up with my stomach.

I called the company where I got the shake from and told them what happened and on my next bottle of Protien shake I will get a discount. I am now on a first name basis with some one from the company I ordered it from.....

Man....so many cravings, I am hungry but not, I am craving soda and can't have it, and them darn pototo chips.

 I fly to California in October, 2011.  My surgeon is there . I am excited and nervous. I can't believe how much will power I have and not having soda for that long, shows me things about my self and also I need to get off the pototo chips........
