I have had these on my long trips (12-15 hours with breaks) and have had the following observations -

1. They give an instant energy boost totally removing the sleepy or drowsy feeling one gets -
a) Early Morning due to early start (after less sleep in the previous night)
b) Post Lunch, especially if it was a late lunch

2. The energy boost comes as a wave and subsides pretty quickly leaving one as much more sleepy and tired than before. The energy wave typically lasts about 45 min - 1 hour for me.

3. From what I have figured out, these drinks digests whatever was left in the stomach at a very rapid speed giving the energy boost, and hence, I invariably feel hungry after 1 hours of drinking these.

4. From this experience, I have developed a way to maximise their effect - Stop Over, eat something sweet (like chocolates), drink a can after ten-fifteen minutes, wait ten more minutes and drive away. This will give a boost lasting up to two - three hours and the energy drain feeling at the end of it would be less. Plus, one can keep oneself topping up with chocolates every 45 minutes after taking the drink.



These are my observations.
Please share your opinion/ experience regarding this thing which can potentially become a boon for long drive fatigue beating.
