I have been vaping close to 6 months and have started to dabble into DIY. I don't normally vape menthol but every once and a while I do like something cooler. I have Strawberry Chill 8 mg from liquidxpress that I like it but find it has too much chill. I usually reduce the chill by adding more strawberry flavor and nic juice. I would love to make a 12 mg watermelon chill...but don't know what to use to add the coolness to the watermelon ejuice. Any help would be appreciated.
