I did have one, and I fixated on that as being the most horrible thing they could possibly do to me.
In retrospect it was nothing. I disliked having it cleaned ( it tends to get a bit plugged up with mucous) every few hours, and it was a bit disconcerting when they chenged out the original one, for one that was tied on instead of being sutured in place, but it was overall a non-event
It is a bit odd to breathe through your throat, howeer it really doesn't feel as strange as you might think
