I actually have a 5 minute ramp on. It does help to adjust, but honestly I'm long asleep by the time the machine builds to high pressures. What's throwing me off is that when you run the mask test, it builds quickly to the highest pressure, and it almost always leaks on me. I bought an anti-leak strap from PadTheCheek yesterday, because I'm convinced if there was more forward pressured on the front of the mask, it wouldn't even leak on me, and I wouldn't have to strap it to my cranium so tightly.
I've said earlier in this post that I just can't imagine using a chin strap. I'm definitely a mouth breather. For example, I took my dog out walking yesterday, and I tried as hard as I could to breathe only through my nose many times, but I can only do it for a few moments. I just do not feel that I'm collecting enough air. If I lay down in bed, I can more easily do it, so perhaps in time I'll be able to; but I don't feel ready to cross that bridge, yet. Luckily, I think the Dreamwear full face mask will help. But we'll see.
My parents love scuba diving. I could never bring myself to try it because even snorkeling causes mask leaks for me, and it terrifies me to be 30 feet underwater relying on a tank of oxygen and a well sealed mask to stay alive.
