It really sounds as though you're going through bouts of detox overload. Killing off yeasts and fungus can release some pretty nasty poisins into your system that your compromised (hep C) liver may not be able to manage well (ya think?). Yeasts and fungus fight dirty when you try to kill them (hence, your nasty outbreak earlier---typical for that).
I can't answer all your questions about this, but I'd say to back off the bigger Miracle-Mineral-Supplement dose, for now, take a break from the Miracle-Mineral-Supplement for a day or two, then and go back to a much lower dose and ramp back up s-l-o-w-l-y. Your liver needs your help on this one, and a gentle hand. You've overloaded your eliminative capacity here. No sense in making it worse.
You might also try adding FlorEssence to the mix. This stuff can be found in any health food store and essentially works very powerfully and gently to help open up your avenues of elimination and possible neutralize some toxins. It can help minimize discomfort. Use two oz of the liquid concentrate added to some warm water and consumed on an empty stomach at bedtime, and again first thing in the morning. See if this doesn't help you recover more quickly.
Jim Humble (not to speak for him, but...) would probably tell you to keep going, just slow down. Hydrate yourself and include electrolytes (the same folks that brough you "Emergen-C" have a product called "Electro-Mix", which comes in unsweetened packets you can add to water to improve your hydration). PLEASE don't do Gatorade, or any other sugary anything right now. It'll only feed the nasty little buggers, weaken your immune system and push you back to square one.
