What to expect

- - At roughly 66mg/day from Barq's root beer, low energy and irritability are common through days 1 to 3.

A taper plan starting point
- - Try swapping one Barq's root beer serving for a decaf or caffeine-free alternative for a couple of days.
- - Then stop the rest; most people feel only minor effects at this level.
- - Replace Barq's root beer breaks with water, a short walk, or a 20-minute nap to ride out dips.
