I know there's a lot of these, but I can't find any like mine.

Now I've tried a WILD 3 times this week. I'm not sure if it's because I'm sick or what but when I try to concentrate on my breathing and relax, in the back of my head I can't stop thinking about swallowing, even when there's no saliva. I know it should be no big deal but it ruins my relaxation. When I just give up to fall asleep I never think about swallowing once.

Is it just because I'm sick?
