I will tell you I contact pstim company and asked if they have successfully treated a patient with adhd. Wow the reply was we need your address. I then sent reply what does that have to do with question? I then received a response that they would forward to their representative. That was a week ago. So I agree with the post today stating they were going to ask about spine one instead. I have heard good things about that and I personally am not liking the lack of information on pstim attached to ear. So I too am going to talk to Dr about the other one. If he insists I will refuse as my gut tells me no and I trust gut. My sleeping is bad now I can only imagine with buzzing etc in ear I will not even get my couple hours. I will know more next week as I go back in to have staples removed. Please keep posting I think everyone here does care about the outcome of experience.
