I run 6 day's a week for the last 18 months i take 60mgs ir adderall (dextroamphetamine and racemic amphetamine) for the last 2yrs. after running lately i feel a zombie. stimulation overload?

Possible: Being active and exercising is excellent. With the exercise and sweating, you may be losing fluids and the ir concentration of the meds causes an overload and increased effect as you describe. Since you have become active, discuss with your dr. And the 60mg which is a relatively high dose, can be lowered possibly. Good job, keep up the good work.
