  • She hasn't even mentioned my snoring!! When I read the story on your website I understood EXACTLY what you were talking about. I have been single for years because my snoring is so loud. As soon as I get to the stage where a girl stays over, I never hear from them again. Your program has taken my snoring down to a low hum. I now have a girlfriend and she hasn't even mentioned my snoring!! ♣♣♣ http://t.cn/AigiN2V1
