I think what has to be said or advised, has been advised in previous comments..

But one thing i need to ask you, TS - Are you a very stressed or tension person? Whether from work, family, creativity, etc.

Eating a good diet, and cutting the bad stuff is one thing.. (not eating enough of the good stuff is also another).. But I do know that people who are constantly stressed / tension, lack good sleep... Also have high cholesterol.

I myself am guilty of that. I'm slim (underweight, actually) , do not smoke, do not drink, once awhile eat some cake with wife (shared).. But my cholesterol (LDL) is high, and hard to bring down.
HDL also hard to bring up, even though i always eat proper diet.

No no, not the 'driving and angry' kind.. That one more to blood pressure. Haha..

More like those really all the time tension / stress type... Always worried. Also will increase LDL. So if you're not like that, then most probably just your diet issue.
