Torrefaction

I have to put ear drops into my tubeified ear for 3 days.  Last night--the first time doing it--I discovered that there is now a clear path from my outer ear into the back of my throat, via the myringotomy tube and the eustacian tube. Yecch!  Last night and today I've had an upset stomach....from the eardrops.  Hamlet's father would sympathize.
