Anyone stop using their CPAP?

I have Sleep Apnea and use my CPAP every night - I hate it, but its better than going without. One of the things people close to me ask if I'll be able to stop using my CPAP eventually. Not really sure if it'll work out for me and I would want to do a sleep study to double-check once I lose more.. but has anyone been able stop using their CPAP?
