A: The teeny-tiny amount of caffeine in decaffeinated drinks is so inconsequential that it really shouldnât affect your sleep (generally less than 5 milligrams per cup, compared with 100-plus milligrams in regular coffee). There are a couple of reasons why your beverages might keep you awake. First, if you order decaf coffee at a restaurant, you may not be drinking actual decaf.

Best Answer: Well coffee can help keep you awake and caffeine does stimulate the brain. But if you want something to help more than try an energy drink. They usually have a few B vitamins which helps. They often have Taurine and ginseng which are also stimulants and can help with the brain too. I would actually try one of the healthy energy drinks though.
