Well, today was my first day back and it was good. Busy, but good. I have a very sedentary job, so I had to go for a walk to get steps in and keep moving. That was one of my problems pre-op too.
I made pre-portioned meals and snacks: pureed soup, 4 oz of cottage cheese, a small container of yogurt, etc. I also ordered protien shakes, protien water, and bone broth to keep in my office when I need it.
All of that and it was still hard to remember to eat on schedule. I only got in 3 meals/snacks at work today, and I should have had 5. I was busy on calls and in meetings, and it just slipped my mind that I should take care of myself.
So I can only imagine how it will be for you! Remember to take care of yourself, and you will be fine. Water FIRST! Dehydration will make you go down before anything else. Then make sure you eat, protien first. Rest when your body tells you it needs it, regardless of the emergencies around you. You can't help anyone if the first responders are tending to you!
Good luck, and tell us how it goes!
