And all of a sudden my shakes make me sick. I drank them since day 1 post op and only the past three days, after only 2 or three sips, it sends me flying to the bathroom in a sweat and coming out of both ends (sorry tmi). I've heard of lactose intolerance after surgery, but I've been fine with skim milk, cheese, yogurt, and all other dairy. Thoughts? I use the premier protein shakes from Costco.

I've been lactose intolerant most of my adult life and can tolerate cheese and yogurt but not milk or much ice cream (now I don't eat it at all). I have been drinking the Premiere shakes recently and haven't had an issue. Your mileage may vary. You may want to try some protein powder in your yogurt or mixed with crystal lite. That's a bummer. Hope you feel better soon.
