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).
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)
