From TFA: Qelbree "may increase suicidal thoughts and actions in some children with ADHD, especially within the first few months of treatment or when the dose is changed,"
Tylenol is widely considered a safe drug even though overdose of 4x the normal dose is near certain death. You do have to watch out for these things.
In this case, medication tends to report silly things as side effects because they report every single thing the patients are experiencing. There's no frequency of reports here, but it could be just a few reports with no causation established.
I also have great hope for the psychedelic research that is starting to happen again. Anecdotally, I have highly improved focus control when under the influence of low doses of LSD or mushrooms (I prefer mushrooms because they feel more "organic", if that makes sense). I am preparing to begin a regular mushroom microdosing regimen, because that focus control does fade in-between experiences when I take 1g weekly. I'm not after the reality-altering properties of psychedelics (except the very rare use of DMT for a "kickstart", as the last big trip I had with that gave me six months of focus control and ADHD mitigation). I plan to take a quarter gram every other day.
Since the US makes it so hard to get (you have to renew your prescription every month) it's actually very likely you'll stop it.
