Glad to hear you're feeling better, Insomniac. I don't have any personal experience with pill withdrawals, but I know how horrible it is to not be able to sleep. I suffer from a medical condition that sometimes keeps me up at night; a couple weeks ago I slept only 2 nights out of a 7-day span. And I know what you're saying about not being able to tell if you were asleep; you don't reach a deep sleep, but you're having dreams. It's a really weird feeling.
Great job staying off the pills, and I hope your sleep returns soon.
