I agree with the 'saving documents' theory. I use eJuice Me Up for my DIY. It comes preloaded with some recipes and allows you to save others. You do have to input the data the first time. After that the only thing you really need to change is maybe your quantity that you are making. Even with the eJuice Me Up program and the document saving. It is not a bad idea to save a cope of your recipes to the cloud or keep a notebook. The notebook idea is nice for making notes if/when you make changes to a certain recipe and are wait to see how it turns out before you make another adjustment. JMTC....
Yo, eJuiceMeUp not only comes with a bunch of pre-loaded recipes
and allows you to save your creations in the database and/or alter the pre-loaded
to your taste, it also facilitates printing neat'o 5x7 " cards like those cooking recipe collection cards.
You could print 'em on card stock or put holes in 'em and get a vaping binder.
