Try the vitamin patches if you can't take chewables

You could try liquid vitamins or vitamin patches. I used Barimelts for the first 3 months, which I prefer to chewables because they melt in your mouth so you don’t have to chew them, but if you have issues with sublinguals, these might not work for you, either. The only thing I have to take sublingually is B-12, and you can get that as a shot or nasal spray.

I struggled with this as well the chewables I will put them in a little bit of water to dilute them or juice it did help but honestly the vitamins were the worst part for me

Typical for who and there personal circumsances? Hasn't been two weeks yet so I would say 9lb is pretty good. Reset your expectations.
First few weeks are a bit skewed...there is surgery weight (as in IV fluids and inflammation), weight loss from pre op diet (and if a lot lost then don't expect to lose a lot in the first few weeks post op), body getting use to the various post op food stages, surgery day weight, gender, incidental activity levels, hydration/dehydration levels.
If you are going to stick around, it would be helpful if you filled in your profile, weight, height etc, it gives context to any questions and helps frame responses.
It is difficult at this stage to meet goals, a calorie goal is probably even more difficult. Focus on water, protein (very helpful for healing/recovery from surgery as well as helping feel satisfied), volumes etc.
What calorie goal has been set for you at this stage of your post op progress?
