Craig, I add my welcome and I too am sure you'll get through this with flying colors.
I can't speak to some of your situation, but I did have a trache tube for a week or so and found that all it prevented me from doing was speaking. Dunno about nasal tube and how that would constrain you so I'll let someone knowledgeable advise you on that. The trache tube is a drag when it gets clogged up and has to be suctioned out.. boyoboy... but otherwise you get used to it quickly. There are also obviously a lot of other issues involved with the ND, but you'll be at a CCC so the docs and nurses will really know their stuff! (I see you're in Palm Springs... are you going to City of Hope, or maybe UCLA or USC?)
Keep us posted and ask any questions you can think of here.
Good luck, we'll be thinking of you on the 21st!
