so I'm able to use my cpap regularly now, I fall asleep with it on. I still have the air swallowing problem but it's not a big deal anymore.
I feel better than I used to, but I'm still fairly tired day to day.
I used this website to calculate my pressure settings, suggested it at 6, but I've seem to have gotten better results with 8. Should I try putting it up to 9 or is that too much pressure? I'm not that heavy of a guy: 165
Sounds like you are still guessing at your therapy, as in your previous post. After 12 years since your last study, and not using it for that period of time, you need to update study, and equipment, for all the reasons previously stated by those more knowledgeable than myself.
All you have to go on is how you feel. So if you feel better at 8 than 6, then that seems to me to be a fine place to rest for awhile. But we can't really offer much help as to how your therapy is going for you. You'll need to provide much more data before we can offer much advise. I can say that the pressure required isn't necessarily related to your weight.
