Ok, it's probably not actually spackle.
I've got a nasty cold. Now, if I breathe deeply it makes a wheezy sort of noise. It's not like asthma (I'm asthmatic), and it makes me want to cough, and sometimes I cough up ... well, spackle.
Is this mucous coming down from my nose? I thought that ended up in the stomach (yum!). Is there anything I can do to cough it up more effectively? It's really interfering with my sleep.
