I bought some pharmacy grade niacin from a warehouse on the internet. I had read a study conducted at a local university which showed it to be effective in reducing cholesterol. But, 1/2 of the participants did not complete the study do to averse effects of "flushing". I remember thinking....those wimps. So I ramped up to a large dose of Niacin and things were fine until I forgot a daily dose. I just resumed the usual dose the following day.
As a result, I began itching....and scratching....and itching more and scratching more and things got out of control. I had set my ass on FIRE! I didn't have enough hands to address the intense itching that was permeating my body. It was horrible and I was in full panic mode. If it didn't slow down when it did, I have no clue what I might have done. Now, I take a statin drug. So much for home remedies. I would think Niacin has a valid use in the interrogation process. Who needs waterboarding, when you can induce flushing. Oh, I forgot to mention Gout. While on the Niacin, I had two episodes of gout in my ankles. This is a painful condition caused when the body's ability to dissolve niacin is exceeded. It can accumulate in joints and cause pain and inflammation. So I had difficulty walking for a few days with each episode of Gout. Never had another episode after discontinuing the niacin.
