I keep all my mixes in Evernote. Just switch back and forth from my juice calculator to Evernote and back again. I have developed a solid Crunchberry, a decent custard, a number of RY4 tobacco things, 1 or 2 strawberry, some peanut butter juices as well as flavorless vapes. If I could not buy commercial juice I would survive. My return on my diy investment has been lax I guess is what I am saying. Yea, I need to work harder at it as was recommended.
