I do one cup of black ice coffee 5 days a week in the morning on the way to work. Caffeine has a lot of beneficial effects as well:

1. Caffeine improves reaction times and logical reasoning. As a sports performance coach I encourage all athletes to utilize caffeine when performing.

2. Study's show that it may reduce the risk of Alzheimer's and dementia.

3. Caffeine has a positive effect on our memory.

If you simply don't like the taste of coffee you could also get caffeine from drinking tea or even taking it in pill form.
