I am so impressed with this product! It's fun to take (pop rocks anyone?) but it also tastes good and give an energy boost!The very first time I took it, I was really dragging at work and knew I needed something to make it through work and the typical mom duties. I noticed a difference faster than I realized, I no longer had the exhaustion that made me want to go lay down. I was able to work thru the afternoon, and getting kids and dinner. I consume quite a bit of caffeine every day (tea or energy drinks) but now I'm starting to second guess just exactly how much caffeine I'm actually getting, given how well this one pepped me up!I would def recommend to those who go thru an afternoon slump, hadn't slept well or just need a little extra energy to just function! I'll be sharing with my husband, I think he'd really appreciate these on his busiest of days!
