How do you take the supplements? Do you take them frequent dose (every 4 hours and waking up in the middle of the night to take them again)? I suggest you do that with cilantro and chlorella. I recommend taking breaks from chelating every so often. Continue taking the chlorella for a day after you take a break from using cilantro. I also recommend drinking lots of water, saunas, selenium and Vitamins C and E.
There are other things which can help, but there's divided opinion about what's most effective and I haven't tried most of them, so I don't want to make a recommendation. Perhaps others can make suggestions.
It took me 6 months to feel better, and a few years to reach the point where I'm hopeful I can stop soon.
