Glad #3 helped you sleep #58606. It's my fave because it feels like a gentle pulse almost like an ear lobe massage. Also interesting that setting #3 on the BT7 is very similar at 7.83hz to the CES "C2 Theta Use to improve sleep for those with insomnia due to a racing mind. 3 Hrs 6-8Hz"
Another related thought: These brain machines are in a way doing automatic acupuncture for you. I think your results might improve if you can focus on some of the things that may be at the root of your anxiety/trauma when use your BT7. If you notice the troubling thoughts lessening in intensity after doing this then it is working.
