Just out of curiosity what is the nicotine content you are putting in? 11, 16mg. I noticed in the beginning with super low nicotine I would get cravings so you might want to consider starting with 16 or even 24mg.
In the beginning, that is all there is to it. Fill and Vape! After awhile you will need to replace the cartridge and clean it eventually, but for now you are good to go. Just 5 drops or so into the cart. And welcome!
