7 months is nothing. You’re in the honeymoon phase. Everyone with a recent adhd diagnosis thinks life is rainbows and butterflies but you’re on a stimulant drug. If you give someone cocaine daily they’ll tell you the same thing.
I’ve been on and off heavy stimulant meds since 2012. They only work for a short period of time. Dosage needs to go up. Consequences need to be managed. At some point you’ll hit a ceiling and they will no longer be effective. It’s just a matter of time.
