Hi Ides, and Welcome to HealingWell BATINEZ!!
I have the familial/genetic cholesterol myself - both of my parents tested positive for that and so did I. That is why, they tell me I had my Heart Attack at 46 and my carotid artery surgery when I was 49 and all the rest that followed - though of course, I can't blame only that. I smoked, and didn't eat very healthy either.
I've taken Zocor 40 mg. for over 7 years now and that along with folic acid (which was prescribed for me)...I try to eat pretty healthy and my cholesterol has remained at a very good level.
There are so many new med.'s out there now - perhaps checking in with your cardiologist and letting them recommend something different for you might help?!
I wish you good luck, keep us posted and don't give up!!
