I can't believe what a difference it has made for me. If you're looking for a healthy way to have more energy without popping pills, try the XS challenge. They have 11 different flavors with zero carbs and zero sugars that all taste great. They are competitively priced and come with a 6 month 100% money back guarantee with free return shipping. I get a couple cases a month and love having more energy to live life and do more with friends and family. Let me know how you like them. I highly recommend the cranberry grape or the citrus but which one is your favorite? They even have teas and cola flavors. I found them on the net at www.sbartz1.qhealthzone.com and I know they can and will do wonders for you too if you give them a shot. Take care everyone and hope to hear from you soon! Warmest regards, BHN

I think I answered this on the General Health board. No, I haven't tried them, but I would have to check them out and make sure they have no caffeine since I take 3 different heart meds and can not have any caffeine. I see you said it had zero sugars, but if it contains any artificial sugar, like aspartame, I can't have it either because it triggers migraines. I'm going to check it out though.
