Not sure where to post this but had to share.
My DH snores, badly enough that we often spend nights in separate rooms. When we went to stay with MIL he didn't snore at all, all week. I was talking to a friend about it and she said "do you have feather pillows?" Answer "yes". "Does MIL?" "No"
When we got home I changed his pillow to a firmer, non feather one and he hasn't snored since!
I'm not saying it'll work for everyone but it has to be worth a try right?
