FWIW, you can build up a tolerance to the flushing effect, but it requires
that you raise the dosage slowly over several months, and take the niacin
every day without fail. Taking aspirin a half hour beforehand, and taking
your initial doses just before going to sleep (so you're asleep when the
flush hits), also helps.

I've been taking 3000 mg / day of standard niacin for the last 4 or 5 years
(1000 mg in the morning, and 2000 mg before bed in the evening). As long as
I take it religiously, the flushing does not occur.

But, if you stop taking it for even a few days, you'll lose your tolerance
to the flushing effect. I found this out the hard way a few years ago. I'd
run out of niacin for about a week before I could get resupplied, and when I
took my standard evening dosage, I flushed badly, and turned bright red. I
had an important business meeting the next morning, and was very glad I
didn't discover the problem then :-). Within a few days, the problem went
away as I reacquired my tolerance.
