Your article on niacin is timely. In 2013, I had hives so badly for months that I could barely function. Back then, my cure ended by just one good niacin rush [300ml]. Recently, I presumed it was fleas, so attacked that idea for weeks, when I then realized, NO, it's hives! I then took 300 ml. niacin, got an itchy rush, did it again a few days later, started to slowly recover. Then, a week later, BY ACCIDENT, I took 1000milligrams!! I survived it better than I thought, & now days later, I believe my full-body hives are seriously on their way OUT! True that I had to bear with rather uncontrollable itching for 1.5 hrs. via the niacin, but that's it. I'm SO relieved this idea occurred to me as a possible way to flush my skin. I was in hell. I hope this helps someone else!
