Hose management - Instead of buying a commercial hose holder, I made a flap in the middle of my hose using masking tape. (I made a couple wraps around the hose wrapped masking tape and then fashioned the flap with a couple extra layers of tape.) I punched a hole in the flap, put a small nail in the wall above my head, and hung the middle of the hose from the flap on the nail. If you have a head board that would be in the way, you could tape or tie a hook on the headboard.
Blankets - the wife and I are both restless sleepers and both of us are "cover pullers." After a couple of nights in a row of being woken by a large tug and hearing "you're stealing the covers," I got the idea of us both having our own blankets. That has made a significant difference in both of our sleep quality due to fewer sleep disruptions.
Light - We installed darkening curtains in the bedroom and got rid of the nightlight. I cover my CPAP with a dark towel since it lights up so much when I turn it off to go to the bathroom. I find this makes it much easier for me to get to sleep and to get back to sleep. If my wife is reading when I go to bed, I wear an eye mask.
Eating - My pulmonologist says you should avoid high carb foods and most food before bedtime. I don't eat sugary things but I almost always have a glass of milk before bedtime since we eat dinner early. I hate waking up hungry in the middle of the night and I love milk so it works for me.
Alcohol - If I am having a drink or two, I try to ensure I drink moderately and that there are a couple of hours between my last drink and my bedtime. That reduces or eliminates the wakeup halfway through the night feeling not quite right.
Consistent bedtime - I try to get to bed around the same time each night so as to get enough sleep.
Mask - Keep trying them until you find one that works. My new CPAP provider suggested I try the Mirage FX. What a difference from the ComfortGel Blue I had been using! I have not been woken once by the air blowing in my eyes or on my face. SleepyHead confirms that impression as well since my leak numbers are way down too.
