I am sorry that my experience didn't help much and your white spots are more than what I experienced. I am also so sorry about how things are going...All I can do is keep you and your husband in my thoughts and prayers. I do understand though about staying positive...I have (knock on wood) been very lucky so far but continuously am on the look out for signs...hopefully they can catch this and do something for your husband. Sue is right though attitude can help...
