I had a lot of trouble this Winter with by lungs and I have been taking CS
on a regular basis.
 After several trips to the Allergy doctor and a couple of changes in
prescriptions with only a small 
improvement I bought a nebulizer (less than a 100$) and used 15 PPM CS in
it, this I did 2 to 3 times a day
which kept my lungs clear but I could not stop as it would come back. Note
we had a problem with standing water
in our basement at work and nothing was done till OSHA was called in. Well
guess what when the water dried up 
my lungs cleared, there was some thing growing big time down there and it
was in the Building air supply. 
and  because of my allergies it was affecting me more than others. I will
keep an eye out for water
in basement if it comes back they will fix it right away or OSHA will be
called back in Only next time it will be
reported as a sick building. When there is a complaint of a sick Building
(all HELL breaks lose)monitors
and sample tests, the whole works. I have decided that what ever it takes I
will not put up with that again.
