HAS ANYONE HAD THIS

I'm 3 days out post-op and I wasn't offered anything like this.  I feel better today than I have so far post-op, but I am still far from "normal" yet.  I would have been interested in something like this even if it is pricey, since I've tried IV vitamin supplements in the past for other things with good success.  I think it is a good idea, especially when the first few days post-op (at least for someone like me) people have a hard time getting in the required protein and supplements and they are just getting used to the constant sip, sip, sip to stay hydrated.
