Hi Anne Marie,
I lost my voice for just about 4 weeks, all I could get was a whisper and I, like you, had to force that. It's not uncommon and shouldn't cause you any concern. Boy did I HATE it though! I love to talk

My voice now is normal although I cannot scream like I could before radiation, it will make me cough.
I also had horrible dry mouth at your stage of the recovery. I would wake up at night and my mouth would be so dry and my tongue stuck to the roof of my mouth so badly that I would feel anxious and scared. I thought that was how it would be for me for the rest of my life. Within about 4-5 weeks that resolved and pretty soon, I could go all night without a drink.
Everything you describe is normal and will get better. Patience is the key!
Minnie
