Query: These are amazing... better than flexeril / skelaxin / etc...

Found a bottle of these in my medicine cabinet from a few years ago... omg I had forgotten how incredibly well they work. I had been taking prescription medications for my leg and lower back cramps; two of these tablets, sublingual, work INSTANTLY and relieve the cramping better than any of the Rx's. I don't know how they work... I just know they do, like magic. Thanks Hyland's.
