Unhappy, very sorry to hear this. I was lucky enough to avoid that but it was on the table until the very last minute everything started moving. I walked A LOT at the hospital because they tell you it helps. I was not allowed to eat or drink anything but an occasional ice chip.
Those NG tubes are not fun either but after the 5th one I had it down pretty good. The one in the ER looped in the back of my throat, the next one came out when I vomited, the next one I think fell out, the next I accidentally pulled out then they had to reposition it like 2-3 times and every time they Xrayed me to make sure it was right, but it wasn't until the last Xray and repositioning.
I am with you I never want to go through that again but you had it much worse with surgery. Hang in there it gets better!
