Tell me all the things. please.

I am going in for my annual check up tomorrow and I am going to be asking for a referral for a sleep study bc my DH and everyone who has slept near me is pretty sure I have sleep apnea. I am sick of being dog tired all the time and I also don't want to die in my sleep sooooo……

But I am nervous.. and I'm wondering what to expect? how bad is it really? Will I even be able to sleep??? Have any of you done one and what was it like.

Also, if you have a cpap machine or something does it really work and is it easy to use or will it bug me and be a waste....??
