So I have a question.
Do you vape different flavors when dropping nic levels or do you vape just one?
In my case, I vape different flavors. Though, in that sometimes you will find little a variance in strength of liquid available when you drop down.
5,10,15,20,25 versus a 6,12,18,24 system for example ... So though I may vape 15's normally, I might not be able to get that at another vendor, so 12 or 18 will have to make do. In practical terms, I really can't tell the difference.
If I vape 24 all day, I get a headache, and if I tried to vape 6 all day which I've tried, I get irritable and edgy. Everyone is different in that regard, that's just how it was for me. The numbers scheme above though, combined with vendors being out of stock of a certain strength, show why there is a variance of what I have in mg strength more than any other factor.
