Now that I no longer practice law, nothing keeps me up. I sleep like a baby, until my bladder says it is full or the dogs tell me it's time for their breakfast, whichever comes first.
In my case it's the cats. Because there is no "snooze" button on a hungry cat.
We got a new Tempurpedic matttress last week, and if anything, I sleep even better.
To the OP, I'm sorry that you have trouble sleeping and I'm not making light of your problems. If not the VA, then maybe you can find a social worker or therapist that can help you.
