The song is about the difficulty of quitting methamphetamine.
"It's hard to believe I don't feel a thing" (after a few days of meth use, when the body's endorphines are depleted, the user experiences feelings of emotionlessness)
"...bliss that ain't real" (the heightened level of euphoria caused by the increase in endorphine output from meth use)
"I found a mountain of pure endless energy" (many meth users will stay up for days or even weeks at a time)
"Once it was a break that I could keep" (he used to be able to control his drug use [pre-addiction])
