Hi Jayney,
I am only going to be wired for hopefully a few weeks but I'll give you my impressions on it so that you can be prepared.
The first day I came home completely wired shut I nearly had a panic attack. It's hard to explain but it's very claustrophobic not being able to open your mouth and I was very worried that I would have to vomit. This feeling goes away pretty quickly - within a day and you start to get used to it. Hopefully your nasal passages are clear as it will make it much more of a smooth transition.
Additionally, it has been very hard for me to eat anything thicker than a smoothie. A lot of creamy soups I can't even get through the wires. One thing I have been living on for the past few days is KFC mashed potatoes with gravy diluted with milk - it's a delicacy after having only "eaten" gatorade, milk and ensure for the past week.
Try to learn quickly how to use the syringe to eat. I guess because I have a smaller mouth, I have to stick the syringe to the back of my teeth and pull away to separate the cheek from the teeth in order to eat anything more than broth.
I also have a very hard time talking. I know some people can talk easily even when wired shut but for some reason, I can't. I can speak fine but the sound gets muffled trying to go through my splint and is very hard to understand. I use text-to-speech on my computer a lot to talk to family and friends.
All in all, it sounds terrible and it's not fun at all but I've gotten used to it pretty quickly and it will be over before you know it. Best of luck. Oh, and you'll get a nice diet out of it as well. I'm down about 25 pounds.
