No advice is needed as you're totally working it already. You really should NOT be doing a lot of exercise on IP so don't feel it is a limitation. Your limitation will be in your mobility, so get some things to help you. If you don't have a 'magic bullet" or something like that, get one so you're not having to "shake" things if that would injure your healing. You also will be drinking lots so is going to the washroom going to be a problem? (don't need to know -- just asking a 'hypothetical' question
I would also just make sure you talk to dr about your vitamins before surgery. I know some vitamins (Vitamin E I think?) isn't good to take before surgery and I'm not sure if that's due to thinning blood, or incisions not healing -- but there ARE some vitamins that you shouldn't take.
On the other hand, my friend recommended I take "Arnica" before my surgery -- orally and as a cream on the area that was going to be bruised. I remember it being sweet, so it may be too sugary, but the cream maybe would be something to consider. You use it before your surgery, but then also after on any parts not covered by the bandage
The good thing about your 'recovery time' is you'll have time to come visit 3FC, read past threads, get some new recipe ideas etc. Enjoy that "down time" to relax, rest and heal.
Oh, just thought: make up some veggie purees, some pancakes or muffins, and freeze them now so that whoever is your "gopher" can just nuke you your IP friendly food.
