I decided to give this a try after I kept crashing midday. I'm not a fan of coffee and many items with caffeine don't give me energy. These didn't have any real sort of aftertaste to it. That was a really nice thing because most of the pills I take have horrible aftertastes. This pill that you take once in the morning and once again at night will give you energy all throughout the day without making you crash mid-afternoon. This is available on Amazon . I received this at a discounted rate in exchange for a honest review.
