Take a sip every time:
- Carrie is about to go into a crying fit.
- Carrie goes off her meds.
Take a drink every time:
- Chris Brody appears in a scene for not much longer than a Stealth Hi/Bye.
- Carrie executes some impossibly daring plan that happens to all work out.
Chug the whole glass every time:
- Dana Brody gets screen time in a subplot essentially unrelated to the remainder of the series.
