Like many here I had serious sleep apnea. During my sleep study I stopped breathing for 93 seconds straight. The technician woke me up and put a mask on me immediately.
I knew I needed the cpap, just have to jump through the hoops. I think the severity of the sleep apnea has an influence on how you take to the machine/mask because like others here I was like a duck to water.
Things that really surprised me; not having to get up to pee. That stopped immediately, sleep right through most nights now. Heartburn went away 99.5%, almost never need an antacid now, used to have a bottle of tums on the night stand. There are other unexpected benefits but those two really stand out.
