Drug Company Niaspan ads

I have been taking Niaspan for ten years to raise my HDL to prevent heart attacks and strokes.

A few weeks ago I began to notice a lot of TV ads for Niaspan which is a very expensive drug. Those ads came out in advance of  a study about the effectiveness of  the drug that proves it is not effective for reducing heart attacks and strokes. I bet the drug company knew in advance of the ads that the study results were about to be released.

Now what do I do? I am waiting for my doctor to investigate and advise me. This drug has unpleasant side effects and if it is not doing me any good I want off of it.
