Hey Dex,
I'm sure you've discussed this before, but have you talked to your doc about a sleep aid of some kind? Maybe Ambien, which clears the system very quickly (after 4 hours), and doesn't leave you feeling groggy. Like I said, I'm sure you've talked about this before, but I'm inherently lazy and don't want to do a search...
