That is to say despite me not being anywhere near the shape I was in in high school, it looks like I'm going to have to damn near mainline caffeine until my adderall supply is sorted out.

That's a mood. I'm on a 4+ year waiting list for diagnosis and I'm on 450mg a day of caffeine and still needing to nap. Too little and my brain is racing while my body doesn't wanna move, too much and I wanna go to sleep. Got a sweet spot at about 3 energy drinks a day.
