I assume you have a cholesterol issue. Why not ask your doctor for a prescription for a statin medicine? You can get the drug for $4.00 a month or less, and it's much less invasive than Niaspan, in my opinion. I tried Niaspan years ago, it wasn't effective, and I would get a huge 'blushing' feeling, my face would flush and I would be miserable. Statin drugs are very safe and in my opinion, very effective.
