Hey Flipflop! Congratulations on your surgery! You really had a lot done - you are really brave! My doc suggested gravol if my pain meds made me nauseous. Maybe you can call your doc's office and ask if something like that would be ok for you to take. I found that the nausea settled done when I got accustomed to the meds - and I found sleeping as much as possible really helped too! Quite a few folks get packing. I had some to, but it fell out with the first BM. For others it took a few days. I wouldn't worry if it doesn't come out right away. I think garlopa's advice about have a BM in warm warter is really good - that might help make the BM more comfortable, and it may help with passing the packing as well.
I hope you are doing well today! :)
