The bipolar-level manic highs and depression/lows are very real.
The feelings of suicide and hopelessness creep up; I have enough personal awareness and grit to ignore it but it feels awful.
To avoid that creep-up, the best thing I found is to have “break” days at least once or twice a week. That is, no pills.
I doubt your daughter or others with ADHD have that luxury though.
I’m not saying it’s not possible to have those side effects, I just haven’t experienced them.
I've had to be very careful about NOT using those terms when talking to doctors and psychiatrists. As a layperson that description seems to fit, but it causes huge red flags for medical professionals and they freak out, resulting unnecessary tests and evaluations for my kid.
The key term for the "manic" phase after the meds wear off is "Rebound Effect". Also when the dose is too high the generally accepted term is "zombie mode" or "zombie-like". Calling it an "overdose" will really cause people to freak the fuck out.
