Another fever's kicking in The shivers in my bones begin A little switch I'm flicking off And on The longest nights are rolling in Naked flames on soaking skin I don't wanna let it go I think it's time That we set it up Reactions in the chain Set it off Don't let it stop I can't get enough It's from within us It's chemical It's chemical Cover my face in broken hairs Can't disguise a broken man Wanna turn my cravings off And on Such a messed up circumstance In my shoes a stranger stands I don't wanna let him go I think it's time That we set it up Reactions in the chain Set it off Don't let it stop I can't get enough It's from within us It's chemical It's chemical Inside my mind it's getting dark A steady beat of a racing heart I don't wanna let it go I think it's time That we set it up Reactions in the chain Set it off Don't let it stop I can't get enough It's from within us It's chemical It's chemical It's chemical It's chemical
