For after surgery, it is nice to have the good quality smoothie travel cups with the canisters attached underneath for the protein powder. Have a few of those ready to go. Also get water travel cups with tight lids to go everywhere you go, at home, On the go, with measurements on the sides to let you know how much fluid you are getting in. Those are what I couldn’t have done without. For when you are back commuting make sure you have premeasured amounts of protein powder every where you spend time (home, office, car). Along with bottled water in quantity for car and work. That way, in a pinch, when you feel shaky and low on protein, you can just mix protein powder into plain water and it will make you feel better ASAP, even if no flavor.
