Sticky has a point- make sure it's not an issue of your bong having some bacteria in it or something.

As far as your bronchitis, you should be coughing- you need to get that stuff out of your lungs so you can get better all the way. Spending some time in the sun might help dry it up too.

In the meantime, if you are going to smoke, just make sure you keep your bong very very clean. Hope you feel better soon:rasta:
