My protein made me sick.

I feel for you and your protien problems.  I am almost one year out of surgery and I still can only drink unflavored protien.  My favorite is 'Vitamin Worlds natural flavor protien powder'.  I drink mine in an iced coffee:
Strong coffee
suger free carmel syrup
unflavored light silk soy milk
one scoop protien powder
lots of ice

Blend the soy milk and protien powder in a blender and let it sit for about 5 min then put all ingredients in a tall glass and enjoy.
I hope this helps you get your protien in, I know I tried a LOT of protiens before I figured out how I liked it. 
Good Luck
Linda
