We have to go to Hancock tomorrow to pick up a new cpap machine. This new one will increase or decrease the pressure as needed. I'll use this new machine for a month and then use the pressures to upload in the machine I have now. My pressure is set at 7 right now but I don't feel like I'm getting enough air. My other machine was set at 12. I'm waking up more tired then when I went to bed. I'm having wicked headaches. I hope that it's just the pressure on my machine.
