You guys are rookies. Look at the times at which you are posting.
I consumed four pieces of Jolt two hours ago and look at me, still going strong at 2 am.
There is a weird flavor to it, but I can easily adapt and it's well masked by a cup of coffee.
OK, seriously, even though it works for late night software development, I find it useful in moderation on a hiking trek - gives me a boost during my late day low periods. Cook dinner on the trail, hike into the dark, hit the wall at 9 pm but you know you want to go another hour, so just a piece to get me over the hump.
I don't rate it a 5 because I too wish they had fruity flavors.
2 pcs ~ 90 mg of caffeine, which is about the same as a single shot of espresso. Compared to a quart of gas station Arabica (~ 300 mg), Jolt is tame. But keep it away from the kids and dogs, because while the taste of coffee will be a hindrance to their caffeine intake, the joy of gum chewing will be a temptation.
