I don't take 4 at once. Here's a morning schedule quickly:
Wake up, Eat... after my meal I take 2 caps.
mid morning another meal then take 2 caps. ... ect.
I reccomend taking them like that after food so it don't mess with your stomach... I've had ZERO stomach problems because I've followed this procedure.
Na, not too wired... I get used to stimulants quite quickly.
