DF... take it at face value. Including the split between refusing to/stopping/just not taking...
Obviously, SHE doesn't see/feel any or enough benefit to be worth the effort.
Some kids are only interested in medications that have impact THEY can measure... it affects which ones we try, and how high we start at... because we have to get a "hit rate" really fast... need the benefits before or as soon as the side-effects. 'Cause if the side effects are noticable (i.e. not life-threatening, but affects how difficult child has to live, like not gettin up quickly from a chair...), and the benefits are NOT noticable... the tendency is to end up with some form of refusal (either outright refusal, or "forgetting").
And yes, bring this up to the psychiatrist. Whatever she needs to take, needs to be worth it for HER.
