To get rid of adrenaline you need niacin. This is because the COMT enzyme pathway that gets rid of adrenaline needs SAMe and niacin to work. Try taking 500 mg of niacinamide before you go to bed and see if that helps. It should help with the SAMe levels, too, because it helps get rid of excess histamine, too, assuming that you have enough B6 and vitamin C for the DAO enzyme pathway.
