Great advice as always Joe he's right about gaba because gabapentin really helps to take away that fight or flight feeling when I first wake up and its helped me with my anxiety which is pretty much all the same thing. Certain drugs like adrenergic agonists I can't get and I can't have any stimulants at all I had to say goodbye to coffee which sucked I even tried decaf and still had an issue. I can't get novicaine, lidocaine, benadryl, or robinul it all puts my heart and nervous system into overdrive. My autonomic nervous system is always hyperactive and in a state of hyperexcitability the panic attacks and fear of leaving the house are the worst sometimes.
