The guy I have recently been sleeping with [ha!] suffers from sleep apnoea. I'll rephrase that: I'm the one who suffers. He snores. Loudly. Very loudly. And then stops. Stops breathing completely, that is.

His snoring pattern looks something like this:
gxnkmnkx... ZNKMX.
gxnkmnkx... ZNKMX.
gxnkmnkx... ZNKMX.
gxnkmnkx...........................
ZNKXNMKGBHX!!

I found this table, which lists the four types of snoring and how they affect the person sleeping with them:

	Group 1	Group 2	Group 3	Group 4
Patient's Complaint	Patient sleeps quietly and well	Patient snores but breathes well and sleeps well with good daytime energy	Patient nores very loudly and sleeps restlessly causing lack of refreshment	Patient stops breathing during sleep and is very sleepy during the day
Partner's Complaint	Partner has no complaints	Partner kept awake by noise and sleeps badly themselves	Partner sleeps in other room	Partner frightened by patient's breathing and kept awake with worry

But there's a fifth group: Partner driven crazy by patient's snoring and kicks him repeatedly, jabs him in the ribs, puts pillow over his head, holds patient's nose and covers patient's mouth, screaming "stop your fucking snoring for chrissake!"
