If you really want to get that punch to get you going nothing works better then bad coffee. When you’re going on a long trip and you’re eyelids are beginning to get heavy just the thought of another sip of that bad coffee can wake you up. It works similar to bad tasting medicine, the worse it taste the faster you mind helps you recover. So from now on I’ll keep that good tasting cup but not far from it will be the emergency bad tasting cup.
