newbiw having prblems with major leaks

hi i have been using cpap about a month and have tried lots of masks - i thought i was going to get good results with a full face mask and did for a few days now i have major blowout at the bottom of my mask and nothing stops the leak i tried a suggestion i read here about getting in sleep position turn headgear to 24 and tighten from there worked a few hours then major blowout cant sleep and dme is closed any clues what i can do atleast for tonight??????

If you can login and post all your equipment it will help others help you as there are many types of masks, machines, and a wide range of pressures that affect mask performance. I sleep with a ResMed Ultra Mirage Full Face that will ONLY work with the forehead adjust to minimum and just touching my forehead with a 2 x 3 cm piece of moleskin on the bridge of my nose and the straps pretty tight. No Leaks!!!!! However; a ResMed Quattro Full Face Mask always leaks because it is too wide for my face!!!!!
