Thrice the maxi-: mum recommended adult dose/24 hrs. is an overdose & the dosing schedule is bizarre, unless you work nights. AMPH are not prescribed on a mg/kg/day basis even in kids, though there are limits for maximum safe doses. Medical complications of obesity ^ risk of heart attack or stroke from AMPH OD. Please discuss getting healthy with your PCP, cardiologist, psychiatrist & psychologist.
