Title: works for me!
Review: I first met this in drinks in South America. The lift of caffeine without the calories in a can of Coke. It works for me. Effects of one tablet lasts about 6 hours, without being hyper and without a crash. Just lots of energy to get things done. Haven't tried it late in the day. Coffee/caffeine tends to keep me awake and guarana may too. For me, the latest I have taken it is about 4pm and it's worn off by bedtime. Since this is a large dose I only ever take 1 at a time and I don't take them every day. But they are great for a day when you want to get a lot of things done... you just keep on going and going and going!
