DIY is a great experience and can be extremely rewarding but at the same time it can be frustrating as well.

Over the past few days I have made close to 600ml of juice, ok, well 200ml of that was Hazelnut, but it's my comfort vape and for me it requires a few weeks of steeping, I would have made a big batch of Rainbow Sherbet but didn't have enough to make that big of a bottle and that is one that I vape daily now.
Just a bit of a recommendation for you, if you have a beaker or syringe I would suggest using those for measuring as counting drops is not precise due to the variances in pipette, droppers etc, for the diameter and the drops will not be consistent, in the long run it will save you some grief if you are going to continue to make your own, you don't want to have to reinvent the juice once you have it down to the way you like it.
