I had mine out about a month ago, all 4 as well.
The anesthetic wore off before I got home, and I thought I was going to die. The pain was horrible. Once I got home and on the narcotics, I was better. I pretty much lived on drugs for about 4 days. By the 5th day, I was doing half-days at work, then I'd come home and take a pill and sleep the pain away till bedtime.
The key to getting through it was keeping an ice-pack on my face for 3 days straight. I had almost no swelling, and the doctor was rather amazed. Apparantely my 45 min surgery ballooned to over 2 hours due to some complications, and he expected a very difficult recovery. By the 3rd day, any apparant trace of swelling was gone, but the pain stuck around.
I can still feel the holes in my mouth, but you get used to it.
Have a significant other bake you a big pot of mashed potatoes. My wife cooked some for me, and I ate them for quite a while. Since soft stuff is all you can really eat, and most soft stuff is sweet, you'll get sick of sweet stuff eventually. Some really salty potatoes satisfy the need profoundly.
Hope you feel better!
