I don't know what to take for mania. I feel chelation has cured most of my manic tendencies.

What you describe could be caused by sulfur. Eating lots of sulfur caused me to experience euphoria, feeling energetic for a few hours followed by a terrible crash.

I don't think it's candida, this would make me feel depressed anxious confused etc.

I am not sure but i read somewhere in the chelation group that coffee enemas are high sulfur and should not be used in hg toxic people. I am not 100% sure you have to look this up yourself.
