Guys, go ahead and holler at me, I am tired and and need some reassurance.

I decided to scrape the label off my jin (I wanted to look at it)and discovered it is a solid block that slides up and down the bottle. I did not notice that before (I was not looking)and I am sure it is mentioned probably somewhere here but I am REALLY feeling lethargic since starting 6 weeks ago. And I am a feeling a little sick thinking about it...Thanks
