avoid congee...they could get stuck at somewhere you don't anticipate.
just drink ensure milkshakes(i prefer the chocolate flavor) until you just can't take it anymore..... (i survived 4 days on ensure/energy drink alone without any solid food)
When they took out my wisdom tooth (all 4 at once), I found out I was allergic to Pencillin, which cause me to vomit a lot.. It was TRUE HELL!!
I was fed ice-cream (which is all creamy and cold and nice), blended soup (cook various types of food, then just BLEND it to a thin pulp), baby food (love squash), and ensure (it's basically a health supperment, you can buy it in most drug stores).
