Looking for protein powder suggestions

I have a recurring problem with the protein powders that I've tried.  Within 1 hour of taking them (I'm Pre-Op) I am in the bathroom with the diarrhea. I can't imagine having to deal with this after surgery. 

I'm not sure if its from the sweetner in them, or from the milk.  I have tolerated both these before adding the powder without problems.

Any suggestions?

Thanks!

You might have an intolerance to the whey protein.  I would try a soy protein powder and mix with water or soy milk.  There are plenty of soy protein powders out there...GNC would be a good place to start.  When you do start the soy protein, do not use ANY of the whey protein.  You want to get the whey completely out of your system.  Hope this helps!

Someone makes an egg protien shake.  Maybe that would go down ok.
