If you are that tired I would stopped coffee enemas and do jus plain water enemas. They ideed help the liver but put a lot of stress on your body.
You could benefit looking on adrenAl fatigue diet until you will balanced yourself a bit and can continue the cleanse after. Try meditation hot shower skin brush plain enema instead of sauna. See if that suits you better than sauna and coffee enema for now then you could try them again.
I stop any reading about health problem after 6-7 pm and just try to do relaxing stuff even cooking and stuff.
Calm yourself down about Amalgams - just do your best to get in better shape with the whole body. If you're tired now with a parasite cleanse - an Amalgams cleanse you break you down. First put yourself in a better condition with adrenal and liver and reduce the number of parasites step by step. Don't push hard on yourself you'll be beter I'm sure.
