My mom had improvement since day 1 I used, she had sleeping issues often (hard to fall asleep but if she sleeps badly one night she has better sleep in another) but before I got my Scalar and GenX she had almost no sleep for 3 nights, then on the first day I used pure scalar with her DNA and did a biofeedback scan at night and ran on remote all night, she had the best sleep in ages and good sleep the following few days, not sure if its coincidence.
