Just something I wanted to bounce of you guys: have you discovered that ejuice's taste and/or vape better after they've sat for a couple days? What in the world is up with that? I have come to realize that this has happened with several different kinds I've had, (and from different vendors). One tasted horrible until about 3 days after I got it, and another produced hardly any vapor until it was a few days old as well. I have pretty much ruled out that it's because of any atty issue. My atty's were functioning fine, and it wasn't with the same ones. I've also heard if you shake them up it can make a difference. Anyone have any ideas as to what causes this? Since there are no chemicals in them per'se, mixing and/or sitting shouldn't matter...ideas?
