I think I am becoming addicted to this device. It is a life saver. Though my headaches continue to be severe this is to do with my not being able to have my normal medications due to COVID 19 & non availability here in NZ until June 2021. The device is helping me get through what is a very painful time & genuinely mean life saving as I had taken an overdose as the pain was so bad & no one had an answer to help until this. I find it reduces the pain which has been constant for nearly three months, I am looking forward to using it once my current headache actually is alleviated as I believe it will reduce my headaches & reduce my future need for pain meds. I cannot thank you enough for allowing me to trial this. It has also helped me get some sleep (have fallen asleep during a few sessions) which I badly needed. Can definitely feel the endorphins etc kicking in the more I use it- prefer that to meds. Will keep you updated on progress. Sincerely thank you Paula Wackrow
