Pills.....

Not sure I follow you. Are you saying someone who let's say is bipolar and after being on Meds. And perhaps getting better no longer needs to take it because they don't want to?
Keep in mind there is a lot of bi-polar folks that can not be medicated. I have tried several of the mood stabilizers, and each time had some side effect pop up that pretty much rule out taking them. And a bi-polar on just anti-depressants can be, well, a bit entertaining to watch. When I tried to take them in the past, by themselves, it was a near constant manic episode......
