Drug rollercoaster
A cycle of using amphetamines or caffeine to feel more awake after a night of drinking, then later using alcohol to feel tired and go back to bed at night, then popping uppers in the morning again, etc etc etc. Dangerous due to the countering effects on the heart and brain.
I've been on a drug rollercoaster all week, I took 3 Adderall yesterday morning after passing out drunk the night before, and drank a fifth of vodka last night so I could go to bed. I feel like shit but I'm gonna pop a few more Adderall this morning and layer a coffee on top so I can function today.
