Amy..I have to agree..the nightmares started when he found out he had cancer. At the start he got terrible headaches also. He continues to have the nightmares which are quite disturbing. I think they will subside. Thank you. Again, this forum is a blessing to me..It gives me comfort, hope, understanding..and a chance to vent..to learn and pass onto my husband what others have experienced with this disease and the treatments first hand. I am so lucky I found it..Thank you all for your replies.
