when i was taking m1t, i started at 15mg and worked up to 35mg(cuz i didn't know how my body would react to it) But i was very lethargic for a while, but u get thru it. At work sometimes i felt like i was about to fall asleep but i kept pushing myself and after about 30min or so it passed. If u take naps, it might not really help. Just push yourself and it'll get better.
