I’m post op 2 weeks. I switched to Core Protein for shakes. Lactose free and real game changer. The elite have 42 Gr protein per shake. Tolerate extremely well and tastes fantastic like a milk shake. Also, no one warned me about the gas. It’s the worst pain. It’s the co2 pumped into you for the procedure and makes you look like a bloated tick. If i was warned i would have been better prepared.
