Sleeved on 5/29 and struggling
Measure out one ounce at a time. (Medicine cups are superb for that.) Then kitten-sip that sucker down and pour another. Keep track. Keep going. Try to get as many of those in as you can.
Your focus right now should be on hydration, unless your surgeon has instructed you otherwise. Mix a protein shake, chill it to suit your tummy's preference, and kitten-sip that one ounce at a time as well. In those early days my instructions were to get six ounces of protein shake in per day total, one ounce here and there throughout the day.
It's work, but you need to do it. I fought for every stinkin' ounce at the postop stage you're in, but that's what you have to do. Hang in there!
For my first week, it was a lot of work to get my liquids in. I don't like room temp liquids either. If cold works for you, keep it cold! I'd worry about getting enough liquids this early out more so than protein. I think I was 4 or 5 days post-op before I even had any Isopure. It gets better. I'm two weeks out now and able to get in all my liquids and protein. it will get better every day!
