Can anyone recommend a anti snoring device?

I am sick of sound of snoring. Can anyone help? He is not overweight and doesn't drink much, doctor says he is healthy. Has anyone had success with any devices? I

I use www.snoremenders.co.uk - seems to work well

MY DH spent £500 on a custom made device ( mouthguard type thing) and it is uncomfortable and has very limited effectiveness. The snoring is slightly quieter that's all but still loud enough to keep me awake. The only solution for us is separate rooms!
