I have had it with any brand,type of protien shake. When I drink them, even slowly, I get super sweaty, shakes, chills , vomit and feel sick for several hours after drinking them. I get a headache and am severaly nauseous for most of the day. It does not matter what time of day I drink them either. Yesterday I was on te couch for several hours shaking with the chills. I keep trying them bc I know I need my 60 grams of protien a day. I'm calling dr. First thing Monday. Anyone eve heard of this ? I'm frustrated.

I couldnt do them try protein to go saved my stomach all kinds of mess for over 2 weeks a little pricey but oh so worth it!!! Im holding more fluids because the shakes and juices were so hard on my stomach!!! 2.5 oz.. Tastes great... 1 2.5 oz bottle 26 grams of protein!!!! Not so sick and nauseous at all!!!!

Hi! I have also struggled with the protein products.The optifast chicken soup made me very ill.I saw my dietician today.He told me that anyone who is lactose or soy intolerant/allergic can get bad reactions to some of the protein bars and shakes.I have been given a special low carb diet of 'normal' food to use with various low soy (my problem is with soy) optifast and optislim food.Good luck - I hope your Doctor was as helpful as my dietician.

Check the common ingredients. Maybe there is something in them? Have you tried pure Whey Protein Isolate with no mixers or added ingredients?
