Guanfacine and clonidine are two non-controlled meds approved for ADHD. They are second line treatments; all the first line treatments are stimulants, because they have the best evidence behind them.
You might want to look at swapping the Tmobile hotspot for the much better deal from Calyx: https://calyxinstitute.org/membership/internet - it's Tmo by default but falls back to Sprint when Tmo is unavailable so it'd add a fourth network to your redundancy :)
My brain doesn't produce the same amount of dopamine as a non-ADHD human's brain. It's morally neutral to fix that with medication, same as it's morally neutral to wear glasses, imo.
