Thanks for your advice David, we really appreciate it. It seems to be working well for everything so far but today it has really started to irritate Steve's nose. His nose is continually running and he said its hurting his nose, plus throat when he swallows. I'm not sure what to do at the moment with it. All I can think is tomorrow when he has hbo we ask someone about it then (its 820pm here at the moment so need to wait until morning). Originally it was only meant to be in until today but then they changed their mind and said Thursday. Fingers crossed we can figure out what's going on with it tomorrow and get some kind of comfort for him.
