Hello, glad your recovery is going well.
As far as the sweetness, you can try to add more milk to the shakes or even water. This will thin them out and cut the sweetness. Or, as @ShoppGirl mentioned try clear protein drinks which you can also add water to cut the sweetness. I liked gatorade zero with protein the best but it was sweet.
In the liquid stages, my shakes and everything counted as liquids. So your shake is counted towards your liquids and your protein. Again, thinning it out adds more liquid to your count too.
It is hard to hit your goal only a week out. I hit my protein and fluid goals around 2 weeks and have been able to maintain them since. You will get in a groove and be hitting goals before you know it, be patient.
OHHH those chewable vitamins are the absolute worse. I couldn't get past the smell, let alone the taste and texture. It was horrible, I worked with my team. I tried every brand and flavor I could found, all gross and I wasted so much money. They were not that concerned, at my 2 week follow up the surgeon cleared me to take pills/capsules as long as I could handle them. I was fine and have been taking capsules ever since. Maybe reach out to your team and ask for help.
