A few general suggestions that are pretty basic and totally doable, MM. Do you take the time to journal and put your thoughts to paper? It's a great way to get your ideas to stop their buzzing, and just give them the expression they're clamoring for. After some time of this, you may notice that YOU are the one who has the ideas, and not they that have you so to speak.
Exercise is another way to metabolize a lot of the energy that makes you feel like a caged lion. Try and make a point of doing something manageable, like just a couple of times a week - but that requires a bit of effort and discipline. You'll feel 'in your body' more as a result, and no doubt kickstarting all kinds of processes that are physiologically good for your mind.
And pipe breathing too. You shouldn't be doing the baha portion of EE of course, but making a point of doing pipe breathing every day could definitely help give you some clarity and calm. Get that vagus nerve stimulated. :)
But the important thing regarding these tools is to be consistent and diligent about using them, as much as possible anyway. In this way you'll be laying some ground work and making a space for the 'shamanic' influences that may be found here, and in other places. Good luck!
