Did anyone try a protein shake on their last day of the clear liquid stage. I’m feeling so dizzy and weak. I’m supposed to start the full liquids tomorrow morning. Will it hurt if I drink a protein shake 12 hours early?

Have you been allowed clear liquids with calories eg apple juice or broth, these may help? That said the dizziness and weakness may not be related to calories but lack of fluids how much fluids have you been getting?

Clear liquid diet post op is to allow time for the stomach to do some healing immediately following surgery (it will be inflammed and swollen). it may be only 12 hours before you can have full liquids but best to check with your doctor, I imagine you'd hate to do something that compromises your health and the surgery.

I never even had a clear liquid phase. It was liquids from Day 2. Day 1 (surgery day) was nothing. Day 2, next day was water & apple juice. I don't think I wanted anything other than that. By day 3 I was on protein shakes.
