It can be brought on by drinking ice water and I’ll cough until loose mucous is expelled. Also,
mucous will accumulate in the throat when I’m sleeping until I wake
up choking. Water isn’t the only time, but it will cause it every time. I am a female, 5’7”, weigh 145, take no medications or herbal supplements. eat foods low in fat and consume hardly any alcohol. I’ve seen an ENT who says, “You have a lot of mucous in your throat.” I’ve tried prescription antacids.
