I only had IMRT so your recovery may be a little different than mine.
1) The sticky feeling only lasted about a month after radiation
2) The taste buds started to come back about a month after and slowly improved. I'm 7 mos past treatment and taste about 75% of most things except Chocolate @50% and Garlic @0%?
4) MY voice was hoarse for about 3 weeks then it got better and then after 2 mos it got worse. Very froggy in the AM and deep. I was told I have that sexy deep voice like Rod Stewart. After 6 mos its almost normal. A little deeper and froggy some AM's.
5)Lot of sleeping problems during treatment and about a month after treatment with the Flem. Ask your doctor for medication for the Flem. It helped a lot. After about a month most of the Flem went away.
6) The 2 weeks after radiation where my worst feeling. Skin was burnt, energy way down, eating still a problem. But then each week it got a lot better. 7 weeks after was feeling a lot better and pretty much eating normal. The mouth sores went away and could eat a lot better.
