My doc said clear liquids and full liquids are different. Trying to get to 48 oz of clear liquids while following a full liquid diet are separate. Also I was told not to drink any clear liquids 15 minutes before eating, 30 minutes after or during a meal. I am now 3 weeks post op and on puréed diet. I’m down 24 lbs since surgery. I struggle getting the clear liquids in but few so much better if I follow these rules.
