I'm glad you found the stickies at the top of the page. That has been very helpful to me. There is also a lot of great information under Cynical One's blog.
What I've learned from SR (and books) is that it won't do you any good to search through his stuff and confront him with pills/drugs. He won't stop drugs until he is ready to stop. No amount of begging, pleading, lecturing, etc., will help.
