For once, Markus and I are on the same side of a feeding tube discussion, at least as to unpleasant experiences with nasal feeding tubes. Much as I dislike the G-tube, the nasal gastric tube was an even more horrible experience for me after surgery. It prevented me from expelling the mucous which then choked me and did cause me to vomit. They had stitched my nasal tube into me to make sure it couldn't come out as they feared my throat was too swollen to rethread a nasal tube down if it did come out, so even puking would not free me.
I didn't need any feeding tube the first time around which worked out best for me.
