I had to stay overnight at the Hamad Hosp, while a couple monitored me all night from another room. I was wired up all over the place, which for me wasn't too comfortable, and then left to 'sleep'... which I did very little of anyway as I didn't like the 'wiring'.
I was also diagnosed by the Maxillo Facial Surgeon, who checked the size of my jaw, tongue etc etc, and noted that this was one of the causes of my apnoea. I didn't do the 'sleeping pills run' as I had an operation instead to alter my jaw and remove a bit of my tongue (sounds gross, but wasn't really that bad).
But this is definitely the route to take, as pills may not be the answer for you... maybe there is something else wrong that can be corrected.
Hope you get 'relief' soon...I know what you're going thru!
