It does get better after a while, remember that you are pulling out a lot of histamines and prostaglandins that your body has accumulated for years.
I started out with 500 mg.
Also, I noticed that after a while, instead of chills the niacin was giving me exhilaration and pleasurable feelings.
I have never tried it, but I do not know of any reason that it could not be mixed in a drink or something. Hmmmm, what an idea! Niacin smoothie cocktail!
