wait... I might know why I'm coughing endlessly during the night. I just vacuumed my bed and all the related things. Now I'm lying on my bed, and I'm coughing less intensive.
Wait... no... 5 minutes later and my throat wants to kill me again. My throat is still coughing, but I just want to sleep. It has been 4 continuous days that every night I was waking up multiple (>=4) times by the stupid coughing. I WANT TO SLEEEEEEEP!!!
I also take a pill of Loratadine, which should stop the allergy symptoms. But it looks like it's not working, so my coughing might not be cause by dust allergy.
@causa_arcana I visited a doctor on Monday, and the doctor gave me Singulair and nebulizer treatment for preventing asthma. I don't know if that's working, since the improvement is not stable, sometimes it feels better, sometimes not. But judging from last night, I was waking up significantly less, so maybe I'm on the right track.
