I usually take 20 mg adderall in the morning anytime from 8-9:30 am. The therapeutic effects for the 4 hours that it’s sold as lasting. The problem is that I have difficulty falling asleep 1-2 hours past my bed time.
And I’m going to have to start taking it in the afternoon. I’ve heard eating citrus helps counteract the effects. I’ve tried melatonin, which has helped to a degree
I’d concur—OP might find that the afternoon medication might actually help with settling down and sleeping.
Also if new to the medication, there just might be some acclimation—I had a lot of trouble back in the day when I was starting meds.
Everyone has different reactions/needs from meds, but I’d also recommend looking at extended release versions, I’ve found them a lot less intense and disruptive than when I had regular adderall.
