If you're snowed in and you are taking a prescribed drug for high cholesterol, you might want to wade through this.

Pharmacologic doses of nicotinic acid, but not nicotinamide, have been known to reduce serum cholesterol since 1955 (22). Today, niacin is commonly prescribed with other lipid-lowering medications. However, one randomized, placebo-controlled, multicenter trial examined the effect of nicotinic acid therapy (three grams daily), alone, on outcomes of cardiovascular disease. Specifically, the Coronary Drug Project (CDP) followed over 8,000 men with a previous myocardial infarction (heart attack) for six years (23). Compared to the placebo group, the group that took three grams of nicotinic acid daily experienced an average 10% reduction in total blood cholesterol, a 26% decrease in triglycerides, a 27% reduction in recurrent nonfatal myocardial infarction, and a 26% reduction in cerebrovascular events (stroke + transient ischemic attacks)."
