Ditch the synthetic vitamins. Cancel the colonoscomy, kill the bugs and decongest the liver. Easy...
Keep some protein in your diet.
All that great food is indeed good for you on a cellular level. The problem is if the liver is congested the poisons the good food purges out of the cells can't be processed out by the liver. Your health goes nowhere, if anything, continues to get worse. Order of cleansing is applicable.
At least you've discovered the parasite connection and colon cleaning regimes, so you're on the right road. A little fine tuning is all you need.
Stay on the bug killer and start flushing the liver every week or two. (Coke flush) The health of the entire body revolves around the liver so any digestive problems that develop (constiptation) the liver HAS to be invovlved.
