I answered 2, for this time, and I'm still on both so I guess, technically, it's one..try?

Anyway, when I naively thought that a drug was supposed to fix it, nothing worked (this was about 10 years ago) more than a couple of weeks. When I attenuated a little bit, it quit 'fixing' me.

Now, since I'm still working and using the tools, the medication has just gotten the symptoms down to where I CAN use the tools with success, so for me that means it's working.
