The premier protein shakes are the best for me. They are 30 grams of protien each and packed with vitamins.
In the beginning it took me over an hour to sip one down, but now it's about 40 minutes. I try to do 2 each day.
I drink Gatorade G2, but I water it down. I like it better then the MIO drops (personally- so many friends love them). So I will pour the Gatorade into 3 different empty 16z bottles of water and then water it down. I do this bc the Gatorade still has calories and carbs and I'm trying to keep my carbs down as low as possible and don't want excess empty calories.
I will drink plain water, but I find it hard too.
I get my premier protein from COSTCO. Chocolate, vanilla and bananas and cream. They have strawberry and caramel on line. I've heard that Walmart may carry it too in 4 packs. It is WAY more paletable for me then any other protien shake so far. I just haven't found a powder that isn't gritty and gross - but again it's so personal, my friend will ONLY drink the powders.
Vitamins are important too. I use patches (patchmd.com) and today was the first time since surgery I didn't wear them...and I felt like crap. Needed a nap and if I wasn't visiting family, I would have stayed asleep...so I think they are helping with my energy. The patches I love bc it's one less thing to factor into my day of "eating" and drinking.
But get in you FLUID! Dehydration is one of the most frequent complications from surgery and it can be prevented (most of the time) with some effort. And believe me, I feel you, it was effort. I set alarms to remind myself to take sips and eat. lol.
I hope you feel better. It takes some time, but focus on healing and the protien and fluids will help the healing.
