My condition started after 2 years of living in life threatening situation which I have had to keep confidential to this day. I slept very little and maintained hypervigilance. Basically continous sympathetic systems ongoing. Even though I eventually recovered my ability to think and feel normal my body changed and my brain goes into spasms of hyper vigilance with very loud noise or agitated people. I tried it all. All. Its tramadol or live like a hermit. Nobody can know. Not even my doctor. But he knows there is more to my story. He is a very wise doctor. I live a double life.
