whey isolate making me queasy?

zkss27

I had been using body fortress regular whey protein in peanut butter chocolate, and I never noticed any problems. Well, I switched to the whey isolate in vanilla, and I get this icky, uneasy feeling after I drink it. I would think, if anything, that the opposite would happen since lactose is supposed to be lower in the isolates, BUT I have never noticed a lactose intolerance before anyways. Why would this be bothering me?!

Go down the ingredient lists. There is probably something very different between the two. I use an unflavored no sugar added whey powder. My daughter (who is allergic to the world) can take it without a problem while the vanilla I had bought previously made her queasy.
