Help?!

Kirsten
So I went to the doctor yesterday to get my first ultrasound I am 6 wk 5 d today and my doctor gave me promethazine for nausea and it made me sleep for 14 hours on the couch(a very uncomfortable couch) in a really deep sleep my husband couldn't even wake me up to get me to go to bed which is very unusual. Anyone else have this experience? Is this normal?
