Linda,
My Drs said the hair on the back of my head will come back.  He did say it may not be the same as it was, probably finer/thinner.  My wife says I have some hair back there no, but it is baby fine type hair.  
I'm not quite 2 weeks out; I've been eating by mouth a little more and more each day.  I started with oats and soup.  Yesterday I had some egg noodles with cheese sauce.  I still have pain/discomfort in my throat; I pray that goes away soon.  I haven't gained any weight back, but I'm drinking the Carnation VHC shakes too.  I hope that helps gain weight. I lost 14 lbs since I started and want to gain most of that back. 
I think the Drs here in TX will release me next week to travel back to my home in GA.  I have my PEG tube scheduled to come out next Wed.  What do you think? I'm a little nervous about getting it out even though I don't use it much any more.  I still don't have any taste, do you have any taste?
