Hey there, fatalframe,
I'm on day 11, and I think day 4 was one of my worst. Actually, I posted on day 7 thinking I was doomed to feel horrible forever, and miraculously the next day things started looking up...in fact, kscott was one of those who helped me hang in there on here :)
I was really nauseous the whole first week so they gave me some anti-nausea medicine at the hospital that I could take home (Zofran). Maybe your mom could could get a hold of something like that for you. I haven't had to take it for a few days now, so hopefully you feel better soon, in that respect. Also, the pain meds cause nausea if your stomach is empty, which sucks since its so hard to eat right now, but if you can find something to get down before you take them it might help keep the queeziness away.
I also had a lot of blood clots, from the nose and throat. So gross. The doc warned me though, thank god. She had me keep a humidifier next me at all times so they would break up and get outta there faster, I do think it helped. I'm not allowed to blow my nose, and I'm too scared to anyway.
I'm also really skinny, and am so terrified of losing weight through all of this. I also am allergic to a protein in dairy products, so its made it really hard to find things I can eat to keep from wasting away. The first few days was a whole lot of chicken broth...ugh. Then as many protein shakes as I can handle. I add bananas, peanut butter, chocolate syrup...all of those are high in calories. The other night I ordered my fave soup from this Thai restaurant and asked them if I could just have all broth, it made me feel good to have something I love, even if it wasn't the whole soup. Eating has been the biggest challenge. I have been cleared for mushy stuff, but I really can't even handle a lot of stuff yet. I just discovered baby food bananas(delicious), and teeny-tiny star shaped pasta, called pastini, that I put with blended up jarred tomato sauce, its easy to swallow and I pretend its real spaghetti and marinara :) If you like guacamole or hummus (I've making them softer with olive oil), those are easy to just swallow too and nutritious. Apple sauce, cream of wheat, oatmeal, mashed potatoes, soup, soup, soup.
So, the gross tongue thing bothered me sooooo much. Its gone now, but for a while I felt like my tongue was covered in slime, and it was. Drinking ginger ale helped 'cause its bubbly and I felt like it broke up the yuck and got it off of there. And ginger ale is supposed to help with nausea, so thats a plus. I took one of those tiny little flosser-brush thingys and stuck it in between my teeth and bands wherever it would fit and then moved my tongue around on it to try and clean up a little bit. It was slow and I had to be really careful, but I was so desperate. It sorta worked.
I have no advice for the drool. I was sooo drooly up until the other day. It just got better as the swelling has lessened. And I'm still really numb all over, I don't think there's much we can do to help that along, just wait I guess.
Anyway, hang in there, buddy. I felt exactly like you are now just last week, and this week is soooo different. I even made it out of the house today to go to a bookstore. You will make it through...I'm pullin' for ya :)
