This sounds familiar, I got to a point a few years ago where even if I could get to sleep I'd wake up at 3-4am with every last problem racing around my mind, but have never felt good with any amount of sleep.
In the end I went to the GP for anxiety and came out with a depression diagnosis and a bottle of Lexapro. Lucky for me I didn't get the crazy side effects and in combination with melatonin at least getting to sleep is no longer a problem.
In the past I've also found that deliberately clearing my thoughts is a way to slip from 'day mode' to those dozy random thoughts, but its often hard to remember in the moment and doesn't always work.
