Today was day one of my pre-op diet. I had two shakes, each a different company. Although I have no other known allergies, I'm clearly allergic to the isolate. I felt like crap all day, burping all day long, got two large hives on the inside of my bicep, and a nagging headache. About 2 hours after I drank the second shake, the symptoms got worse and I started throwing up. As soon as I did, I was perfectly fine.

Did anyone else experience this? Did you switch to soy? Not sure what to do!

Are you lactose intolerant?

If you can reach your doctor, ask them what to do. If they can't be reached until Monday, I'd try switching myself over to soy and see if I tolerated that any better. Read the labels and try to get something that is as close to what was recommended by the Nutritionist. And still try to contact the Doctor's office Monday and see what they say.

If you can take benadryl (diphenhydramine), you could take one or two for the hives.

Hope you feel better soon.

I had to stick to soy or hemp protein. Don't try it again. Hives can progress to having trouble breathing.

I'm not lactose intolerant that I know of (drink milk without a problem). I plan to call the doc office first thing on Monday. Right now I'm eating an ounce or so of low fat ham/chicken every 2-3 hours and I'm ok. I still feel like I want to eat one of my fingers though! LOL

Whey makes my stomach a roller coaster for some reason, and I am not lactose intolerant. So I switched to egg white protein with no prob.
