I recall that you have long-term hepatitis - and liver issues of that severity ALWAYS cause various symptoms & issues with the GI tract (no matter what else is being done).
Slime/mucous in the toilet after CE's is almost always indicates liver flukes and the accompanying liver congestion...and all manner of physical and mental imbalances.
Fwiw, there's no way I'd be comfortable 'self diagnosing' something like "mercury in the GI tract" if I knew I had long-standing hepatitis and was exhibiting mucous/slime after a CE. The digestive disturbances caused by both can be very extreme (and change in severity & presentation at various stages - and various stages of cleansing).
IF#1/#2 to cleanse and get pressure off the liver; full parasite cleanse; daily CE's (or twice daily); nightly castor oil packs; Liver Flushes consistently every two weeks for as long as it takes to 'break through' and then after that until the 'amount of debris coming out becomes consistently less' from the previous flushes. Do a 5-day liver cleanse before each of the first Liver Flushes to ensure adequate prepping.
