You're getting on the ride I just got off.

Oh, it's a blast and I'm sure you'll have fun while it lasts.
Dizzy head spinning colors excitement et al.
A pit of the stomach feeling fear of the fall.
Fizzy scenes fading behind thumping screens and the uncanny feeling that it means everything.
Tingling fingertips and back of the throat drips that sink into an endless pit of elation/pleasure/despair.

You're getting on the ride that i just got off of.

I'll be waiting here after you've had enough.
