Thanks. I never get sick but I had a killer sore throat. My nurse sister told me to gargle with warm salty water which helped the pain. Then I read to gargle with peroxide. I've never heard of that before but I did that too. Broth soup and ice cream were heavily called for.
Since I was very young, about six years old, my mother advocated the salty water remedy for sore throats. I like your endorsement of the ice cream method.
Not really "gurgling" (oh that is a lovely onomatopoea!) but definitely the sound of water rushing through a pipe. It would start suddenly, run for a few minutes and stop just as abruptly.
Took me ages to trace it, and I did wonder if the mains feed from the street had a branch to my neighbour - not unknown in 100-year old homes and in fact my first house was the middle of three served from a single stop-cock.
Eventually, after clearing out the accumulated earth filling my neighbour's stop-cock chamber, I discovered the sound's source...
... My under-worktop freezer.
It has a fairly wide vocabulary, and occasionally really does sound like water flowing in a pipe.

A few years ago, not long after moving into my home now, I heard quiet but very odd, bubbly gurglings apparently from below my other neighbour's conservatory. She identified the sounds - a croaking frog.
