My husband is unable to breathe at night. He has tried Advair and other types of asthma medicine and they have all failed. He has resorted to drinking because that works, unfortunately. He has developed a tolerance and now drinks a 15 pack and half a liter of vodka to breathe. He also gets nauseous and vomits once a day usually soon after eating, that started about two weeks ago. If he does fall asleep, it last a couple hours and he wakes up gasping for air, but he can't get any so he stays up miserable. Also, he describes it as slowly suffocating because it feels like an overweight man is sitting on his chest. What could this be? He is only 22.
