I've found a great supplement that can really get me focused and stay awake for hours. It's an amazing product and it's not some type of speed. It's a blend of vitamins and caffeine. I guess that's why people drink coffee to stay awake with the caffeine. I don't know how the researchers did it, but it has been working really well for me and doesn't feel anything dangerous like 5-hour energy drinks.
I used to drink those, but then I still get tired with those shots. With this supplement called Liftoff from Herbalife, I'm getting a really good kick out of it and actually not bothered about not being awake enough. Of course, the person has to put in his or her work with having proper nutrition and also exercising on a regular basis in order for all of that to kick into gear and work well.
