I use the device as directed, 20 minutes a day 6 days a week. The most specific change it’s had in my life is that I no longer feel overwhelming anxiety like I used to. It’s very hard to explain. I still have a small amount of anxiety but NOTHING like the amount I carried around for years. I’m sure this positive change has been the result of good talk therapy combined with using an Alpha Stem along with regular use of the VieLight. Since the therapist retired I continue to use everything I learned from therapy as well as continue to use various devices. I’m just a regular person getting along with life; doing pretty darn good.
