I'm wondering if I should stop eating earlier in the night. Someone mentioned caffeine. I do drink a lot of diet coke. It's a very unpleasant sensation and distressing because it happens suddenly and as somebody else posted on this sight, It feels like I'm choking. I'm going to go to bed with a strepsil in my mouth and see if at least the tickling and irritation goes away.
Another sufferer here. I'm 18 and have been spitting up green mucus every night for at least 2 years. I'm apparently not allergic to anything, and it doesn't improve when I stay away from home either. I've had a couple of sample tests and both were reported to be free of anything growing in it. I've been to ENT a couple of times too, and they did sod all to help me. They suggested it's a post nasal drip, and gave me nasal sprays/drips that didn't help at all.
Now, I do sleep breathe through my mouth - it tends to dangle wide open - and I wondered if this is something we all have in common. Perhaps the answer lies in getting myself hypnotised into breathing through my nose while I sleep. I do seem to have pretty crappy nasal passages though. Theyr'e always at least partially blocked, not to mention a somewhat lacking sense of smell.
Also, the only nights I've ever had free of phlegm was after I'd had a rather nasty operation done on my chest, where they basically took it apart and stuck a titanium bar in to keep it in place because it was growing lopsided. Maybe it was the strong antibiotics I was on, maybe because I wasn't moving, and in fact barely breathing. (fun times!) Perhaps it was "cleaner" air, although I seem to remember being free for a while after I came home, or it might just be that I had bigger worries and subconciously swallowed it.
I read trough the replies, and a few times people mentioned mold. I've had the same problem for about 2 months. The mucus just builds up when I go to bed until I can't get any air trough my throat. That's when the coughing starts, and it lasts for about half an hour. then it kind of settles. It's getting less, but on some days it just gets back to the old where I wake up at night once or twice.
I was already wondering if that could be the problem since I have some mold on my wall, near the floor, right where my head is when I sleep.
But my girlfriend doesn't have the cough even though we sleep in the same bed most of the time.
My bed is now on the other side of the room, I got rid of as many dust as I could, and I'm going to try washing off the mold, so I hope it gets better from now on.
I'll post here if it gets any better.
I too have suffered with this for years and it only occurs at night whilst lying down. I keep water on the bedside table and have a sip or get up and have a sip of something fizzy to clear the throat. I do often have to cough up/spit up phlegm, which is always clear. I suspect mine is a combination of allergies (both pollen and food) and I do occasionally take antihistamines and expectorants. Hot drinks such as lemon in water, green tea, peppermint tea, etc, all help.
I would suggest the person who mentioned 'clove' actually meant the aromatic clove and not a clove of garlic ...
