Go a week without any caffeinated products.
Then you can go back to coffee again. You've lost sensitivity to the caffeine and developed tolerance. You have to cycle it, most people make the mistake of drinking coffee all the time. Which is fine if you just like to drink coffee (as I do), but if you also need the energy from time to time (as I do) you have to not drink it all the time. Otherwise you develop tolerance, have to drink more coffee or get more caffeinated through energy drinks, shots, etc and when you do stop taking in caffeine you will feel very tired and/or get withdrawal headaches for a day or two. Caffeine tolerance develops very quickly, just about a week. Which means if you really want the same level of energy you have to go no more than a week or two max of drinking coffee every day. Especially if you drink several cups a day or more.
If you don't actually like coffee to enjoy, then try "stepping down" (caffeine wise, love it as a drink) to green tea. If it doesn't do anything for you, well that's because you are used to coffee-levels of caffeine, something like 100mg to 250mg. Once you go down to soda (60 to 80mg), then black tea (30 to 60mg), and green tea (20 to 60 mg) it's not as much an energy boost, but definitely helps when you drink a few cups a day. If you are really tired, you can then go back to coffee once in a while for extra energy.
The plus about green tea (or oolong, white, or lightly brewed black teas) is that you wont get side effects like feeling excessively tired after a few hours or caffeine withdrawal. You can drink it as often as you want. Gyokuro green tea is on the higher side of caffeine for green tea, but still about the same as black tea, and is what I like to drink most often. Dragonwell is my second favorite.
I like chocolate, as well. You want 70% cocoa or higher. I like Lindt, but if I had the money I would eat Amedei Porcelana and Toscano Brown more. Rich enough that a square or two a day is all I would eat. It doesn't have enough caffeine to be a substitute for coffee, though, not unless you eat a ton which is likely to make your stomach hurt. All the naturally caffeinated products tend to be acidic and boost your metabolism. The plus about dark chocolate -and I mean the extra dark 70 to 90 percent, "real" chocolate which doesn't have more than 4 to 6 grams of sugar per serving - is it also works as an appetite suppressant, not just a mild stimulant. You would think not, since chocolate it is associated with fat people who can't control their appetites, but that's milk chocolate or cheap dark with a ton of sugar. The plain bars that are mostly cacao are surprisingly good for you, very rich in antioxidants as well. Just don't eat a bar or more a day, only a square or two or a serving depending on the size of the bar. You wont get more than tea levels of caffeine from chocolate, though. Which isn't bad if you are also drinking tea.
There's always caffeinated soap, as well.

I ordered a few bars from ThinkGeek 2 years ago, smelled very minty and nice. Does wake you up, but it might be more from the smell. I doubt much of the caffeine really makes it through the skin, but it's still nice but pricey soap.
I drink energy drinks as well (mostly flavorMonster, NOS, Full Throttle, or cheap Red Rain: Watermelon), but like with coffee I don't consume it all the time.
Both energy drinks and coffee are fairy self-limiting for me, I know to stop for a while when I start getting heartburn. That's the downside of acidic beverages.
