Steep: 4 Days - 1 Week (Drop Eucalyptus & Mint to 1% for shake-n-vape. Honey will probably still be overwhelming without a steep, so if you can, make a dilution and cut it to 0.125%)
INW Eucalyptus w/ Mint is definitely the star here, offering a wonderful cooling sensation and enjoyable throat & vape. The lemon or other fruits here just offer a nice accent flavor that blends well with eucalyptus w/ mint so your palate doesn't get bored. JF Juicy Lemon is great since it's a fantastic lemon flavor without any unwanted throat from citric acid that other lemons offer.
If you don't have FLV Honey Bee, you can probably sub FA or TFA in its place, but I personally liked the Honey Bee. I tried it without the Honey and found it not quite as enjoyable. It offers a nice sort of floral sweetness to the mix. Honey also takes a while to steep to be enjoyable, otherwise it will just be too forward and in your face. I liked it at 2 drops in 15ml, but feel free to bring it down to 1 drop so it's not so prominent. I feel a lot of people would probably prefer at 1 drop.
Feel free to try subbing your favorite cherries, berries, other fruits, etc with Eucalyptus w/ Mint to create your perfect Cough Drop
