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.

Term first used by R&B singer Vivian Green in her 2002 single "Emotional Rollercoaster" from the album "A Love Story". It is used to describe the varied emotions that a person (usually someone you're in a relationship with) has you feeling for them. For example, your girlfriend cheats on you with your best friend. As much as you hate her for cheating, you can't help but keep loving her because she has you so sprung.
2.) When your emotions go up and down like a rollercoaster. For example, you keep slipping in between happiness and sadness.

Vivian Green: "Boy i'm so tired of you making love to me, and then disappearing so suddenly. 'Round and 'round it goes.
And I'm so tired of you pacifying me with promises you know that you'll never keep......I'm on an emotional rollercoaster loving you ain't nothing healthy; loving you was never good for me."
