Great. The O couldn't wait for your answer and I took five times a good dosage. I'm an I.D.I.O.T.
Niacin flushes out toxins in tissue cells. Perhaps the large dose released so many that they are still floating around forming a rash.
Some people can take 1000 mg or more per day, but they have to build up a tollerance to it. Not what we want to do however. These that take those kind of doses, don't even get a flush from the 1000 or so they take. I guess that's why they make bigger pills.
I'm sure the rashwill clear. I always err on the low side, I'm a chicken sh.t sometimes. Always worried that my rush will be too strong!! You won't have to worry about that at least, you know what your limit is! I'm sure you'll be more careful the next time
But please, don't give up. Try at least one more time, by the books. Give yourself time to get back to normal first.
As I said, at least 150 or so won't come close to doing what it did this time so you can relax on that worry anyway.
Sorry about your scare though. Sometimes we are alone in these experiments!!
