Anyone else have this problem? You open a tin or jar, smoke a couple pipes with that blend, and then you want to change it up a bit with another blend. So you open a second tin and switch between the two for a while. Somehow a third blends enters the fold, and then a fourth. And then more..... yeah. I uh... have several blends going now. What can I say? I like variety. However, how do you stop yourself from unnecessarily opening too many only to have to waste more jars, in an effort to keep your tinned tobacco from drying out. I've long had this problem. I need discipline, my friends! Advise me, please.
