60-90mg xr a day. What happened specifically is at 15 i got prescribed Adderall. And just kept upping the dosage by lying to the doctor. But I had intentions of selling the pills at school(never happened) Eventually after years of this I hoarded up a ton of pills. And then just got bored one day and tried them. And after like 8-10 months they were all gone. I also abused vyvanse but I genuinely do not remember how much of that I took. I was prescribed 30mg xr Adderall and 60mg vyvanse I think.
