I am a long tern GAD sufferer with periodic panic attacks also. For some time I have been treated with low doses of Zanax on an as and when necessary basis but would very much prefer to be free from using drugs to control the problem. I purchased Alpha Stim device some weeks ago and have been very disappointed with the results with absolutely no improvement in my condition. I also have a problem with sleeping for more than 4 hrs a night which I hoped the AS device would help also, again, no improvement. I have followed all available advice on AS use and have tried many settings in terms of length of session, time of day and strength of current. I have also had some unpleasant adverse effects, sometimes experiencing pressure in the head causing onset of anxiety when using the device. I would welcome feedback as to where I might be going wrong in setting up and using the device.
