Or tea.
Yes, I know. You shouldn’t rely on caffeine for long-term energy. But it can often help in a pinch because there is proof that it is a mental stimulator.
So if you feel foggy or lethargic, enjoy a cup of tea or coffee. See if it helps. If you have a condition that gets triggered by caffeine, please avoid it.
I also suggest skipping the sugar. Avoid the sugar-laden caffeinated stuff, too. It will look like they help at first but too much sugar causes an energy crash not long after. And then you’ll end up feeling worse than before.
