SP, I can understand the being afraid to eat. You don't want to rip anything, no infections. However, you can't allow yourself to starve while waiting for your mouth to heal. How about broth with garlic and ginger in it? They both have antiseptic qualities to them. Plus it's yummy.
I'm listening to a training course online. It's providing a droning soundtrack to my reading here on SR. So utterly boring.
