OKay guys so to make things easier to read. I now have 115ml of vg75% pg25% base with 18mg nic strength. I add about two-third into a 10ml bottle and few the rest with flavor and menthol crystals. Okay first problem is, those flavors comes in such small bottles. How much do you guys usually add into your base? For example for 10ml bottle, how much base and how much flavor do you guys put? I also realized that these flavors are not sweet. What are some good sweeteners to recommend? Thanks guys!
