Misoprostol anyone?

My husband and I went in for our 10 week check up. Baby stopped growing at 6 weeks and a few days... Several after our very first ultrasound when we observed the heartbeat. Doctor confirmed miscarriage today with a higher quality ultrasound and prescribed Misoprostol (as well as pain and nauseous meds). Has anyone used this before? What should I expect as far as how quickly it causes discomfort, bleeding, etc? I want to go into work tomorrow but I also want to get this over with so I can heal. Advise appreciated.
