I have been exhausted for about a year. A friend gave me a bottle of this juice to try, explaining that it was not a burst of energy or a juicy version of red bull. Within days my productivity at home and work increased and I could make it until 10pm without conking out. Bonus is I am sleeping better and after a month it has replaced my RLS medicine and completely ELIMINATED my joint pains AND the ankle I smashed 2 years ago feels like new again! It's CRAZY! The flavor is strong and cranberry ish and you have to get used to it. You have to get it through a MLM source and some folks are fearful of those... but I love that it's delivered to my door and overall is cheaper than all the redbull and starbucks I formerly drank to get me throught The day! It's basically aloe and fruit and it targets cell renewal rather than trying to repair what is already damaged. They say it's great for migranes too but I don't have any experience with that. I am just signing up and this is my first post. Xperia is the first thing that came to mind because I have been analyzing it for almost 6 weeks now. You should try it if you get the chance.
