I have to tell you, every day is a roller coaster.

Emotional roller coasters tend to emphasize the lows, tend to be more affected by the low, by the dip in an emotional roller coaster than when you are at the peak.

Everybody likes a roller coaster ride.

I'm on a roller coaster.

I don't want us to go on a roller-coaster,

There is nothing like the indignity of not fitting into a roller coaster.
