Best caffeine boost I've tried!
I don't drink coffee (it upsets my stomach). Using very strong black tea sometimes helps me, but it was getting to the point where I was relying completely on Extra Strength 5-Hour Energy to get through my day. I was going through a bottle a day, which adds up to around $100/month! Yikes! I am very happy with the Smart Caffeine supplement...I take it as soon as I wake up in the morning, and it gives me long-lasting quiet energy. I only rarely have to take more than one a day. Not only am I able to be more focused and productive, but I'm saving a boatload of money as well. Very grateful for this product!
