Hi,
I thought I would add my experience as well.
I had a surgical abortion at 7 weeks, and I had IV sedation. At the private clinic I went to, they required a driver to take you to the clinic, wait in the waiting room, and take you home. Technically, you shouldn't drive after you've had sedation, but if you get a ride to work maybe, you should be fine to work.
After the procedure, I felt just fine. I only bled very slightly for 2 hours afterward, and any cramping I had went away as soon as I was able to stand after the procedure. I didn't feel drowsy or nauseated afterward. Like lucy315 said above, I actually went to get food with my ride (boyfriend) right afterward.
Please remember that every woman is different, but the experiences I read online were nothing like I experienced, I had no complications. I'd also like to add that Lucy315 is correct that it can take quite awhile for the entire process to be done (the procedure itself takes about 3-5 minutes but the waiting and paperwork and recovery take a little longer), but in my case I was in and out of the clinic in 2 hrs and 20 minutes (my poor boyfriend was keeping the time, he was so worried).
Good luck, and I hope everything goes well for you.
