Simvastatin is the generic for Zocor, IIRC. It's cheap (my 90 day prescription is $4).
I've tried everything, Ben, plus I'm a vegetarian and so eat no red meat, a major cholesterol contributor. I still do fish oil and oatmeal, but other things I've done are Guggul, Red Yeast Rice (which did help a little), plant sterols, etc., etc. My doctor long ago determined I had no dietary reasons for having such high cholesterol, so he absolved me from guilt on that regard. I later found out both of my sisters have been on Simvastatin for years.
