Meditation really helps. It is all about training your brain to sit still with itself. 10 minutes a day just sit somewhere quiet and focus on your breath (I don't go for mantras . Notice your thoughts coming in and then just let them go. The point isn't to not think, the point is not to get stuck in a thought. Timed writing also helps. Get all that clutter out of your head so you can focus.

One of the reasons I think acupuncture works is the meditative aspect of it. You have to lie still and be calm because you have needles in you I say go for it, it cannot hurt.
