it 'can' make you really aggressive aswell though cant it?
No it's not like alcohol.

yeah but i mean does it have amphetamine like effect .... like acid ...
where thre's NO WAY you're gonna sleep ....
Well it is a moderately potent stimulant, your first few times you will have difficulty sleeping. Street tablets of ecstasy tablets also commonly contain meth which will keep you up all night.
Either way I still usually feel alright in the morning.
