Bests & Worsts Reviews from Amazon

(Left is the one I bought at CVS v.s. right is the one sold on Amazon) The first time when I bought this, it was from the one sold at CVS. And It really worked, I decided to buy the same 10mg tablets on Amazon. I expected the exactly the same shape and quality, however, the one sold on Amazon has completely changed its shape, taste and quality. It doesn't work at all, I feel like just eating tasteless candy. It used to be like as soon as I take in one or two, it numbed my brain, and I felt asleep real quick. I thought Natral has changed ingredients, so I just gave them a benefit of doubt and I used it all until I bought new one again, this time I bought at CVS. Then again it proves that Natral hadn't changed anything. I really doubt this product on Amazon. The package design is also slightly different. These things often happens on Amazon especially for medicines... I'm considering quitting my all medicine subs, I'm searching different stores. Disappointing.
