Caffeinated, Sleep Deprived, and Overwhelmed? Welcome Home.

Nearly 90% of the adult population drinks caffeine on a daily basis. For most people, it’s part of the daily routine, like putting on pants.

However, you’d be surprised how much caffeine can affect your overall health and mental well-being. For example, people turn to caffeine when they’re emotionally exhausted, but caffeine can’t cure that kind of tiredness. As a result, caffeine can backfire and leave you feeling more anxious than you started.

The answer isn’t QUITTING caffeine, it’s drinking caffeine strategically.

Using Caffeine Science, GreenEyedGuide will show you how to feel more alert with less caffeine. How to enjoy your coffee without jitters. And how to regain your sense of control when you feel exhausted and overwhelmed.

GreenEyedGuide believes:

  • Getting enough sleep is important, but not always possible
  • More caffeine isn’t always the answer
  • Someone who is fully rested or fully caffeinated can still feel burned out

If you believe the same thing, you’re in the right place.
