about a month ago I was sitting on the couch and everytime I tried to breath in I would caugh. I could only take very short almost no breaths. I went to the emergency room they said it was broncial spasm. Well now this happens when I am asleep. I will wake up at three or four every morning caughing having to take very shallow breaths trying to get air. This is very scary and very frustrating. Please help. I have tried albuteral it does not help at all. The only thing that seems to help is breathing treatments. Can someone tell me what this is? and how to get rid of it.

thank you.
