Well just got back from the gym, and on certain days that I have a lot of work to do, I will take Adderall throughout the day. It def does the job, but when its time to lift, I sometimes have sharp pains in the left chest area, cant tell if this is gas or heart pounding so hard, im getting pains.....(dont think i wanna experience this again) Any other fellas take adderall or have similiar experience??
