Was in the hospital a month ago for 1 week on IV antibiotics for a serious wound. Here is how I managed:
-First, you must get the doctor to write up your menu as “regular” or whatever your hospital uses to denote it’s not a restricted diet, and the patient can choose whatever they want. This is vital. I told my Dr I was on the “anti-cancer ketogenic diet”. He said Hmmmmmm… we really don’t have that one on the list. But I convinced him I was competent to make the choices, so he wrote it up as “regular” and let me fill out the daily menu choices.
-Second, fasting is not very effective if you are in for very long. They get worried and will try to intervene. They “charted” everything I ate and drank, or did not eat. Found out the first day that to say “I’m just not hungry” was to cause problems (I just skipped lunch totally, which sent them into fits). They interpreted that to mean I was worse! I didn’t eat a whole ton of stuff after that, but enough to keep them off my back. And some places will not even discharge you unless they are sure the whole digestion system is working right (both in and out, ya know?).
-Third, I was totally PICKY. I ordered things like a protein, hold the carbs (croutons, buns, bread, etc). I ordered extra mayo packets, or butter or or 4 (yes four) half n halfs for my coffee. I did manage to sneak in a little container of pink himalayan salt that I was liberal with at all meals. I’d order a “real” egg omelette, hold the fries/hash browns, and order a side of sausage. All in all, I was just picky, and refused the sugar/starchy stuff. And always asked for a lemon wedge, that I put into ice water. Oh, and I’d order the “cheeseburger” sans bun, and ask for mustard and extra mayo. I always had to repeat it, since they weren’t sure they had heard right.
I always chose the simple stuff, without sauces and breading.
-I drank coffee with lots of half n half; herbal tea with my stevia; lots and lots of water with lemon wedge; and for nausea did drink diet ginger ale. Yes, not the best. But infinitely better than another drug pumped into me.
-Be willing to eat mostly the same things, in case your hospital has limited choices. It’s only for a short time, no biggee. Never had a need for friends to sneak in stuff. I will admit, though, not all hospitals have as good of choices as this one had.
Hope that gives some ideas.
