1) Sure, potential for added certainty would be nice, as long as it isn't too expensive.

2) No. The meds have greatly improved my quality of life compared with last year and before. If it comes with a proviso of pulling the plug on something that is working, even if it is working to treat something unknown or different?? Seems like a high cost low reward choice. Heck, I don't know that I'd be let back in the house if I were "off my meds" as it were. I used to be a royal pain in the butt to live with.
