I used to drink protein shakes often before and they've never caused stomach pains or anything like that. Now that I am starting to drink them again they are making me sick. I get an upset stomach and feel sick after I drink even half of what I used to drink before. It's the same brand and it's not expired. It's never happened before.
What could be happening?
Any help would be nice! Thanks!
