I don't plan on DIY to the point of handling concentrated nicotine, but I'm a newbie who has spent a little too much money on mail-order juices that turned out to be too weak in flavor.
I noticed one site gives an option for "extra shot" of flavor -- is that something I can do myself? If so, suggestions on how much I can add to already-flavored juice? I see on this forum "use the recommended amount for that vendor's juice." OK. So subtract 50% for the fact that my juice is already flavored? Subtract 75%? Start by adding 25% of what is recommended into a 10-ml bottle of my regular juice then add a drop or two every time I decide a carto-full is boring? (I have larger bottles from the vendors, I use the 10-mils for mixing to get what I want, like pg/vg, WTA, weaken the nic with 0% juice near bedtime, etc, so I could do the flavor-shot mixing in small bottles.)
If I like 555 from Bloog, whose 555 flavoring might I like?
Thanks for any hints.
