I bought a bottle of Mio Energy Green Thunder flavored from the local shell station. They had coupons for $1 off so I figured I would try it. The liquid water enhancer was added to 3 bottled waters and I drank them before noontime. I did not seem to experience any added boost in my energy for the day. I had no better alertness. I however did not drink my usual 2 cups of coffee. Though I also did not experience my needed alertness I get from the coffee instead I felt somewhat drained and dragging by 2pm.
