Oh my :cry:
You're not an emergency, that means life threatening. You are a priority. The surgeons hands are tied by the system. I find the system quite frustrating at times but since my last stay have knuckled down to play the system.
PALS are at the M&S entrance I think. First port of call.
I would let Andrew Wan put a tube in. Horrid, horrid, horrid but the feed is life giving. You need it, that's undeniable. I would get that asap. I was as thin as you in March, you need calories.
I would wait it out for the main man for your bypass. And stay chained to your bed until you get it. If he's not on call this weekend, I presume he's not in to Tuesday. I was lucky when I was in, that he happened to be on-call.
