Assuming you have the right chlorella then you can try frequent dosing like every 3 hrs during the day and 4 hrs at night. It does work for some but Andy has had oodles more experience and says NO to that because for most it doesn't work. But if you are not using Prime Chlorella or Pyrenoidosa type from biopure don't even bother.
Not much you can do about the adrenals since they suck up Hg like a magnet so you can use the Adrenal Miracle Mix to get you past this hump.
