I posted about it in the sleep forum thread I opened yesterday but WOWSERS! I am so happy with the results I can hardly believe it's really this incredible after one night's sleep! I am in virtually NO Pain! I am so happy that it works this well, I just can't tell you all how much better I feel, it's like night and day! I made the straps on the headgear as loose as I could without letting the mask (a nasal one) leak and I don't have a headache at all isn't that awesome? I was expecting one and poof not happening.
