Yes, the "unknown" is maybe part of the HARDEST thing in all of this! So many "what ifs." Honestly. I had to continually talk myself off the ledge cuz like you, I'm very Type-A and used to being in control of my destiny. LOL--not my tummies little bia*ch.
As everyone said. HYDRATION.
Believe it or not, getting your fluid in will make you FEEL more in command! It's even WAY more important than protein at this point. You can live for months on your fat. You can live about 3-5days without liquids. And the thing is? The more dehydrated you become, the less food you can consume, the more anxiety you have, the more pain you perceive, and the more depressed or crazy you feel.
So that's your goal.
Goal #1 - Get that fluid in. You have one job. Drink 1oz of water in 15 minutes or less. Use the little measuring cup they gave you from the hospital or hell, use a jigger! I used a 4oz jigger. My one job was to get 4oz in per hour or better. Get the fluid in any way you can:
1. Liquid form (anything clear and non-sugar)
2. Ice cubes/ice chips
3. Ninja "snowcones"
4. SF popsicles (non-creamy kind--just the fruit flavored ones) or frozen clear protein drink
5. Broths
All of these count!
When you are fully hydrated, then you can really address your protein shakes. If they are too thick, thin them down with Fairlife Milk, water, decaff coffee, or decaff tea.
Hope that helps!
