Please help interpret these graphs

Attached are two screenshots; one of a "normal" flow from between two Large Leak Blocks, the second is a series of events. What do these indicate? I have been on CPAP (APAP?) for 34 days and I am not finding much success. I still wake two or three times per night as far as I know. As to the graphs, only the first portion is valid. At 3:15 I took the nasal mask off (PR Wisp) (its new) and slept without it for a couple of hours, woke, put it on at a pressure of 6 if I remember correctly, but I was congested and 6 wasn't enough --I felt suffocated, so I turned the machine off so it would start again with a pressure of 6.5 with Optistart, whatever that is. But I wasn't falling asleep and I felt like I had to breath really deeply to get any air and it seemed like the machine was responding like "Oh, he's getting plenty of air, let's just wait and see" so I noticed that if I opened my mouth I could breath, so I pulled off the mask, turned it upside down and placed it over my mouth. I started breathing really easily through my mouth with the 6cm pressure, and found that I could exhale through my nose, but not inhale. I fell asleep doing that, but I feel pretty crummy this morning.

Any ideas?

Sorry, sleepy stupid me. OK, where's the attach button?

upload the files to a hosting site, (I prefer imgur.com) and post the links to the images that imgur gives you.
