First, only take 1 baby aspirin a day, the long half life will compensate for that. Otherwise you can experience a 4 hours intensely bleeding popped zit, like I have in the past.
Your second dose of caffeine should only be 100mgs as per the research and the dosage of E you are showing.
But anyway, describe the lethargy you experience a bit better. I personally experience a tired body feeling, but racing mind type with ECA, and that is because of the overdrive your sympathetic nervous system running in circles expending nutrients as energy, tiring out your CNS.
