Amazing! Best 45mins of my day with the guided visualisation video on as well. The clinical evidence for the device is sound, and I feel that that imagery session really adds to the effect. But sadly is too expensive on self-pay UK prices. I have done 4 treatments, every other day, so far to get the preventive effect. I have daily migraine and would love to use it for each migraine. I doubt I will be able to afford another device for months, so will likely have to use it to cover my annual treatment gap (local NHS requires annual washout of CGRP injections). But it is keeping this bearable this year, which is huge.
