thanks for the info. i will let my doctor know about this. i haven't felt good since thanksgiving last year. i have had a respitory/sinus infection that just won't go away with a rotten smell in my nose. and my energy level has been at zero for so long now i forgot what it's like to have any! thanks again for the post.

I believe it comes from smoking.  Do you smoke?
