Hey Sarah, Anthony and Rainr I switched to BiPAP on Saturday for second time, the settings were adjusted to be lower so I could tolerate it. I tested it in my chair upright this time, and wanted to see what it felt like before I tried at sleep time. It was weird feeling at first watching my chest wall go in and out so much but I took to it fairly quickly. I tried it that night and low and behold after a lot of nerves I slept with it all night. and the next night! So proud of myself. Hopefully I can keep it up. Thanks for your support. This is an awesome forum - lets get more people on it! cheers, Carolyn
