Here it is 1:30 in the morning, and I'm wide awake. Not because I have a 3 week old baby, but because I can't stop coughing. During the day, my cough is mild and I barely notice it. My FEV1 has gone up by six percent since I had my baby. So, why is it that I lie down to sleep and spend so much time coughing? I do my Xopenex before bed, so I'm open. I've tried propping myself up with pillows and lying flat. Any suggestions would be so very welcome. <img src="i/expressions/coughing.gif" border="0">
