Maybe all the symptoms you are feeling is still the continual dumping of mercury? The CNS can take a very long time to heal... I can tell you from my experience with benzo withdrawal, suffering and symptoms was the process of healing, I dont know if you get breaks during servere symptoms but every time I felt like i was at my lowest point it would usually follow with feelings of health and well being(we called them windows), Mind you it took a couple of years before I even got to a stage where those windows resembled anything normal. In one sense I am astonished how severly damaged my body and mind could get and in another sense astonished how much it can recover. I really must stress that you dont want to go down the psycho-med path, you will be opening up a whole other can of worms. Addiction to these meds can cause you the symptoms you are feeling now... I say keep trodding along with your diet, exercise and whatever else it is you do that helps.
