I had all taken out all at the same time many years ago. Yup, got knocked out which was kind of cool actually. They really did tell me to count backwards from 100 and I got to 98
Mine were impacted and that wasn't expected so it took a second dose of anaethestic to get me through, therefore, my immediate recovery time was a bit longer than expected as well. A reputable place won't let you leave alone. Even to take a bus or a cab because you will be so stoned you won't be able to find your way out of the building. At least, that's how it was for me. Really funny stuff.
The next couple of days I ate yogurt, soft pasta, milkshakes and whatever else I could swallow without chewing. No chewing for at least 24 hours -- I think I went about 56 hours before I chewed. I had codeine for a few days, and with that, I really didn't suffer. It was nice to have someone around for the first day to "look after" me.
Then I got independent, sent my mom home and oh, about three days later took my last codeine around noon and figured I was good to party for the weekend.WRONG!!!
Do not, absolutely, DO NOT drink any alcohol for at least 24 hours after your last codeine. Trust me. I won't tell the tale, but just trust me.
I think I took two days off work. I can't remember for sure, but that sounds right. I had it bad apparently, and really, it wasn't. Don't stress it. Just make sure you have lots of slippery mushy food and a nursemaid.
