i always have to take alot to get rolling and i do it very rarely like once every few months.

im talking like 400-600mg not counting a 200mg-300mg redose shortly after

i weigh 260 lbs 6'2"

seems unsafe but if i don't do this i literally just get a caffiene high

these dosages are guesses

a couple examples of a typical night for me are like 5 small pills ( i snort one to guage and then take the rest ) then later maybe take 3 more.

I never really feel like im overdoing it but im an ex meth addict and im wondering am I trying to get too high from this stuff?

Or is it possible for someone to just tank these things.

even from different sources its the same problem i struggle to get high from it.
