Drinking pickle juice has been employed by athletes for a while to stave off dehydration (of course just small amounts, or diluted). There's a drink called Picklejuice Sport for this very thing (great idea which made the "inventor" a lot of money, but what a scam -- it's like bottling and selling water.
)
Anyway, aside from that and the coffee beans, which I think are good calls, what happened to me was that I had unintended consequences with the practice of vaping spicy flavors too often. In the short term it worked and was awesome, but I exacerbated the underlying issue and my palate started becoming desensitized to anything
but aggressive flavors -- which is fine unless you care to taste subtleties in eliquid. Once I realized that not only was the cinnamon problematic for me on other fronts too (tasting the melted plastic; chest pains), I began searching for "hotter" cinnamon flavors because I built up a tolerance for the spiciness of the cinnamldehyde (the flavoring that gives the spicy cinnamon flavor). Too much of it made it so I couldn't hardly taste anything anymore -- except spicy(er) cinnamon.
