I work shift work. As such I am constantly feeling run down and when I drink energy drinks or coffee I can't sleep later when I really need to. I really did not hold out any hope for this product to be honest. I have to say though that I am amazed and really impressed with this supplement! It really boosted my stamina so I could perform better at work. I felt mentally clear and "on the ball" but NOT jittery or wired like I feel when I drink energy drinks. It felt really, really, natural. Like I was just very well rested, had a good breakfast, and ready to take on the world. It was not a fake energy feeling which is what really impressed me. It felt like it just boosted what was naturally inside me whenever I am completely rested.
It is rare that I would buy or recommend a product like this, but this is seriously just what I need. Something I can take on work days to give me that boost that coffee and energy drinks can't do. Oh, and another thing, it didn't interfere with my sleep like caffeine does. Another reason why I'm giving this 5 stars and will definitely be looking for it in stores.
