I've been taking it for a couple of months now and my doc started me on a 1/2 dose for 4 days and then told me step up to a full dose. I couldn't sleep when I took the full dose so I reverted back to 1/2 dose until this week.

I'm having a much easier time with the full dose now and I can only attribute that to the "stepping system" approach my doctor used. Maybe you could ask your doctor about this.
