I'm pretty sure I have laryngitis and have had it for a few days now. I'm trying to drink liquids, rest my voice, sleep, and all that good stuff. However, at night it gets worse. I have this wheezey cough, and I can feel some tightness in my chest and I can't keep from coughing. It makes it hard to sleep. I've tried teas but it's really only temporary. I have a humidifier up at night but it doesn't seem to do much. Can you suggest anything that could make me more comfortable?
