You could research Alpha-Stim as an alternative. Yes, it's a prescription, and yes, insurance doesn't cover it, but for what it does and the cumulative effects, it is worth the money. I've used Alpha-Stim for >12 years. I paid for it myself on a fixed income because I knew how important it was for my recovery from my car accident and for the symptoms of my other medical conditions I developed following it. It helped decrease the number of medications I need to take.
