Okay, I'll give you the lowdown on getting wisdom teeth out, haha! I had 3 out quite a while ago and was just as scared about the exact things you are. First, I was up front with the dentist and told him. He "promised" me I wouldn't get sick. He also had a really nice office with rugs everywhere. He gave me an IV with valium, decadron for swelling, and I forget what else. He also said I wouldn't swallow any blood, because yes, that does make you sick. When I woke, I felt fine, but realllly tired and unable to get up for a while. Also, I didn't take the narcotic pain killers he prescribed, because those can also make you sick. I just took two ibuprofen and was fine. I didn't have antibiotics either. So definitely tell your dentist your fears, ask questions, and that way you all will be on the same page. You will be fine, I'm sure!! Keep us posted and good luck!!
