Careful with the sweetener! I put a couple drops in my favorite juice when I was using the cartridge and dripping methods, and it was über tasty, but when I switched to cartos it was wayyyy to sweet! Luckily, I was able to mix the sweetened juice into my reorders and it evened out. I don't use the sweetener at all anymore, since I only vape Ms. T's in the cartos, but it worked great with the other methods.
