Having hit my 40's with a vengeance this year and as we know, a lot of things start to .. ahem.. 'go south'... and having the great delight of having a toddler at home with the added promise of varying sleep patterns.. it's fair to say, I have needed a boost for a while.I've been searching for something for a while now to boost my flagging energy levels for one so after a casual search of Amazon, I happened upon this product. Doing a full scan through the reviews one thing became clear to me, the amount of reviews saying 'it really works!'Now, over the years, I've bought many a product for all different reasons with varying degrees of success so I'm likely to be wildly skeptical about another bottle of pills to try.I'm here today ladies and gentlemen to tell you categorically.. after three pills... it works.And I'm here to wave the flag with the myriad of people in these reviews saying the same thing happily.Already within three pills have had a massive energy upgrade, I haven't had to have a siesta during the afternoon because I'm ready to drop, my sleep has been restful and deep and my alertness and concentration levels are through the roof. My wife (bless her!) also approves of the much-needed energy boost and erm... 'other benefits' it has brought to our home. She also says thanks!Lastly, I am here to report that there have been no side effects to taking these so far, no after taste and nothing horrid which would make me think otherwise about purchasing them.A truly perfect product and a delight to take!Do it.
