Hi All, hope alot of you can help me here, i'am scared....my hubby had a failed back surgery a few years ago and is totally disabled..well as of a year and a half now he snores HORRIBLY, and sometimes it sounds really weird, and is very loud that he can be heard all over my 2 story house, i have not slept a whole night thru for this long because he also stops breathing so i stay awake to push on his stomach so he will take a breath, he is so unaware of it, he saw a specialist today and they are going to do a sleep study, to see to what severity his sleep apnea is, exactly what do they do step by step during this study? I'am so scared because im afraid i will fall asleep to long and he will die a sudden death, because the dr. said that is one of the complications of this apnea, what do you think it has done to his heart? please someone...or many respond, im afraid he will die
