of all the varieties of acai berries, I chose this bank, despite the absence of comments in Russian. I work in a very intense pace, constantly in my head to keep a bunch of important information, I certainly tried other means such as echinacea, etc, but they just did not give effect. Get up in the morning, it became increasingly difficult, not to mention that to make toilet did not have the strength. These berries, I had high hopes and for good reason. My husband and I started to drink one capsule in the morning and already half of the banks I ordered two more. Now drink 2 capsules. Frankly, it's hard to remember the last time I felt so cheerfully. The good news is almost all but invigorating effect, they give a sense of optimism and clarity of mind. The word lazy for me now forgotten, moreover convinced that stress is the best remedy. The only problem habits accumulated over the years, when I used to put off minor things, just to sleep at least an extra hour, but now I do not want to sleep during the day, just out of habit I can lie down. Very happy with this product.
