Oh, I definitely understand your fear. Has your cardiologist told you why a target of 70 instead of 100? It may be worth another discussion understand why. Also, ask them how this drug works differently than other cholesterol drugs and if there’s a way to tip your toe in the water a bit to try it. I tried it some time ago and quit after 4 days. I tried again later and was ok taking 1/2 tablet.

I did a search and found an article with this summarized:
‘Why the focus on 70 mg/dL? "Studies have shown that when LDL falls below this number, plaques in arteries get smaller and they stabilize, which lowers the risk for heart attacks and stroke," says Dr. Cannon.’
