“I used the Dr Beck Professional Machine for the last three weeks. I have had problems in the past with Sleep Apnea, and would wake 20 times per night, and have constant problems functioning the next day. Dr Beck phone staff originally pointed out ways I could control my sleep patterns using special Dr Beck frequency Presets and assist with low energy and tiredness throughout the day. Support was there to answer my questions when I was a little confused between the Dr beck traditional Program sets, and the new introduced Delta and Theta Programs for sleep. Using the gel pads on the temples with the Theta Program enhanced a greater sleep period, and I would use the traditional Dr Beck BT-4 frequency on alternate days. Thank you for your amazing machine, Julie Summerton, Arizona."
