I run a lot gone nonstop for the last 21 day's strait I take Adderall (dextroamphetamine and racemic amphetamine) 60mgs a day with no problem. Today I'm abnormally tired but not sleepy. Normal?

Need sleep. Your body cannot run nonstop without enough sleep. Our bodies need about 8 hours sleep a night. Adderall (dextroamphetamine and racemic amphetamine) is a stimulant or an upper and you have not noticed you body telling you to slow down till now. Slow down and get enough rest.
All organisms must. Rest - that includes human. How about working in some breaks for your body to rest. You can also do a cardio mix. Take care.
