Hey Zatt, my son in law gets bad headaches from time to time, and I had told him about BIEL doing the migraine trials. The next time he got a headache, he put an Acti Patch under his cap. He said that in about 20 minutes the headache was gone! He now keeps a patch in his truck in case of headache while working. The device is really amazing, who knows what it can help with!!!
