Hi Lisa,
Well sounds like your first 24 hours have not been fun. Hopefully it is all up hill from here. Sorry to hear about your complications. Yeah, that anesthesia is not fun. I got sick also, but it passed by late evening. Sleeping on the back is hard, but you will find a way. Use lots of pillows around you and you can kind of sink into them sideways and that will help. Just take it easy and remember that rest is your friend.
Keep us posted, but don't over do it!!
Nancy
