Christine D,
Welcome to the site!!
You have found the right place to seek information, ask questions and vent if you need to. The people on this site are caring and compassionate and will listen and try to help you whenever they can.
The fact that you are starting to eat is great. It is a long road but from what I read in your post you are progressing well with your recovery so far. Try not to get frustrated and don't expect too much too soon with regard to eating. If you haven't already done so, ask to speak with the hospital's dietician and/or nutritionist. They should be able to help you and offer many food suggestions and preparation methods to help you out.
You may also want to talk to your doctors about a better sleep aid than Tylenol Pm and possibly a muscle relaxant to make you more comfortable when you sleep.
You should mention your concerns about radiation to the RO. It may benefit you to start a Journal where you write down your questions, concerns, and feelings. Bring it with you to your appointments so you can look at it and not forget to ask your doctors any questions. I'm sure your doctors are used to this and will certainly take the time to answer all your concerns.
I hope all continues to go well for you.
Feel free to PM or e-mail me directly if you wish.
My thoughts and prayers are with you.
Cheers,

Mike
