Reducing caffeine.

Get some fresh air. I get the same way sometimes, and really feel like coffee would be a perfect pick me up in the afternoon. But I usually don't make/buy one, especially with the price of it these days. If you're looking for a pick me up, perhaps take a quick break outside-the fresh air will enliven the senses. Or if you can't leave your job at that point of the day, a simple change of scenery will do. Perhaps visit a co-worker for a quick chat, or get a cup of water.

Lots of ways. Those caffeine replacements made out of barley or different spices help some people. Take guarana or some natural energy booster...that may help too!

I have struggled, too. I, too, have this issue. I have many suggestions. One, is that I've found part of the caffeine boost to be a placebo effect, thus I will dilute my coffee...half coffee, half hot water. This helps some. Another idea is Yerba Mate. It's a tea with caffeine-like effects, but is much better for you. It tastes great, too. You can find it at most health food stores. Lastly, if you are a die-hard coffee drinker, look up cold brew online. I have a cold brew system at home. You make a coffee concentrate, which is stored in the fridge, and then you add hot water. Some how, the process of soaking the beans and brewing the coffee that way decreases the acidity and the harmful effects of caffeine, while still giving you that "I just had a cup of coffee" feel and taste.
