I flush BIG time from niacin but I find that I can get a boost in my HDL which I need in addition to the huge LDL drop I get from Lipitor.
I found something that helps avoid the unbearable flushing.
I have ALWAYS flushed badly at 375 mg. immediate action niacin (3/4 of a 500 mg. tablet.) I take niacin ONLY on a full stomach and can then tolerate 125 mg with no flush. (On an empty stomach ANY amount is unbearable.)
Since my flushes usually last about 10-15 minutes, I figured that that amount of time was what it took to absorb, peak and eliminate or deactivate most of it.
Thus, yesterday I had a decent peortion of spaghetti and meatballs and 15 minutes later I took 125 mg quarter pill, a half hour later I took another and a half hour after that another...NO FLUSH AT ALL and a 375 mg. total!
Thus I am in effect giving myself a SLIGHT extended release formulation but probably no more than 90 minutes...far faster than even Niaspan so it should be pretty safe.
It is a bit of a pain in the asp (like Cleopatra) to do this timing, especially if I am running around outside, but I'll see if I can work something around this!
So here's something to help those who want to take immediate release niacin but not TOO immediate!
