Out of curiousity, have you tried activated charcoal? It's not good to take frequently because it blocks nutrient absorbtion, but if I'm feeling really awful or just need to feel clear for a day so I can focus on something important, charcoal seems to mop up some of the toxic metabolites and give me a short break.
Yes, same – but taking too much or taking it for too long (basically taking more than 2g) seems to be abrasive to my GI system in a way that isn't helpful.
