After many years of being a freight train snorer and trying all the strips and sprays I seem to have fixed it accidentally with a new pack of pillows.
Neck had been killing me so while doing the food shop I impulse bought a new pack of pillows

Been using them a couple of weeks now and DH reports I am eerily silent during the night now, no snoring, don't roll round all night like a washing machine spin cycle.
Neck still hurts though so need to find an alternative solution for that. Thinking I might actually have to do exercise instead of just thinking about it.
