Post-Ops with Sleep Apnea

Does anyone who is post op have sleep apnea? I use a CPAP and was wondering how do you know if you still need the CPAP after you lose the weight? I hate to have another sleep study just for the heck of it, but I didn't used to have sleep apnea and hope it will go away as I lose weight. I see my sleep doctor next Friday, but I really don't have any idea if I still need my CPA*****t. Natalie 281/223/125

I noticed I wasn't sleeping well and was taking the mask off during the night. I had another sleep study to be sure, didn't want to chance it. I was only on a level 5 and did find out after the 2nd study that I no longer needed the CPAP. I was on Medicaid so everything was covered.
