Fadetoblack,
I have followed your posts here about your friend. I find it admirable that you continue to support and encourage him to see his Doctor about this when nothing has been changed yet.
Might I ask, does anyone go to his appts with him? Even if 'Yes' could you not pop along for 'support' and take the opportunity to raise concerns?
Another way, which I do with ALL my Drs because of memory/anxiety problems, is write a list of everything he needs to speak to the Dr about, and bury the statin issue at number 3/4.
I hope your friend gets the treatment he needs, and that you are having a good day yourself.

Dave.
