if it's a straight D&C, you could actually be back at work the next day. I had one done when I was 19 - done because I was getting bleeding after sex. I had no issues - mild cramping but nothing worse than when I had AF. What you need to keep in mind is that after an anesthetic/sedation, you can't do the following things for 24 hours:
drive a car
operate machinery
sign legal documents
give legal advice

You should not drink alcohol for 24 hours. Many Dr's will also tell you that you can't be the sole carer of a minor for 24hrs as well - some say 12 but most say 24.
