No problem DEANNX, here is an update:
I take a total of 3g organic chlorella per day, in the form of two 0.5g tablets per meal. I tried taking 5g per day, but it felt a bit much. I had trouble sleeping, I had a fever-like feeling at night. The tingling and numbness would also be more intense.
With 3g per day, the skin lesions have continued to fade out, except on my calves. I don't think that's a coincidence: My feet are the only places I still feel the numbness and tingling, and still have weird cracked and dry skin. The cold sensitivity also seems more pronounced in my feet. I've got no scientific basis for this, but based on the feeling, I suspect mercury is gradually removed from my body, but that my feet/lower legs still have a lot.
About 1.5 months into the chlorella adventure, I tried an orgasm. The visible inflammation symptoms were there, but I felt pretty good in the days after. Definitely better than usual. However I tried another orgasm a week later, after which I had my usual shitty cognitive symptoms: fatigue, irritability, depression, etc. So POIS is not conclusively improved, however if it really is a mercury thing, there might be quite a bit of mercury in the bloodstream as I'm detoxing, and I'm guessing symptoms such as POIS may improve once most of the mercury is gone.
