Namu 0 Posted May 15, 2016 I was sleeved on 4/22. Since surgery, I am unable to tolerate any Protein since it gives me diarrhea. I am unable to drink milk or use anything with whey. Does anyone have suggestions of what kind of Protein powder or liquid shakes that don't have lactose or milk. Thank you for your help.
