There's probably better ways to do it, but you can compare a known value on the meter before and after you have taken the potion. To get a known value, you can for example take the base energy given by a cookie (like 100 for Brave Cookie Level 1) and add the energy upgrade (or 0 if it's level 0). The energy loss per second ("tick") is 3 on episode 1, 4 for episodes 2 and 4, 5 for episode 3. So you know that if you have the equivalent of 3 ticks on episode 3, you have gained 15 energy.
