Alternative to Anxiety Medication: Anyone try Alpha-Stim?

This is not a sales pitch.

I grew up with ADHD and have severe anxiety. Recently, having breast cancer and managing alone, my anxiety became overwhelming. I looked into medications however my therapist suggested a device called an Alpha Stim. Skeptical at first, tried it and the effects are amazing. It can only be purchased with a prescription.
I use the Alpha Stim daily, it helps with anxiety and insomnia. Medication are better but there are alternatives.

Curious to hear experiences with alternate treatments.
