Why does amphetamine relaxes me?

1h ago i took 60mg amphetamine orally and now im super relaxed and lazy and don't want to do anything, but to melt into my chair. It almost feels like an opiat. It's the second time i do amphetamine and the first time was exactly the same.

Why is that? Regarding PsychonautWiki https://psychonautwiki.org/wiki/amphetamine it should be the exact opposit. Focus enhancement, Motivation enhancement, Thought acceleration, Thought organization Wakefulness ...

I'm diagnosed with severe depression (but take no medication) so my serotonin system might be fucked up, but is there a correlation? I'm gratefull for any insights.

Edit: Only coke gives me all the amphetamine effects. Super hyped and can't sit still.
