Pre-op Meal ideas

Hey everyone. I am 5 days into my preop diet, and quickly becoming sick of everything. I have been making keto recipes for dinner with 1-2 carbs per serving, One protein shake per day (19 g of carbs) and only other carbs are in small amount so cheese or dressing. I was just told no sugar, and low carb. No fat limit. Looks like from reading on here every surgeon is different. I struggle most at work. I am a nurse and tend to get more hungry at work.

A couple questions.....

What is everyone using for protein shakes? I have been using GNC lean protein shakes (25 g per serv)

Were you given a max carb limit?

Drop some recipes in a reply you may have had and are yummy:)
