I was back up to 30 cigs a day. 2 weeks into vaping, I'm down to 3mg nic. Going for 0 very soon.
Good job man.
I've tried going down from 6 to 3 and 0, but find out that I end up vaping a ton more. With a Digiflavor Siren 2 set up for restricted lung-hit on single coil builds (28ga twisted @ 2.5mm, 5~6 wraps), I stick to 6mg and a tank can last a few days or more; it seems to be my happy medium for killing cravings and not killing bottles of juice.
I've tried making my own juice for a while to save more money, but it seemed to get too tedious/messy. Building a new coil every several months and rewicking once every other week is enough maintenance on something like this for me.
In the end, I'm saving money and my lungs are happier they're not gunked up by everything you get out of smoking, I bet you're feeling that too.
On a side note; if you're still looking for small mods, I've been using a Squid Vape Double-barrel v2.1; it's a bit on the pricier side (not crazy high like YiHis), but it's about as tiny as you can get out of a dual-battery 18650 mod, minimalistic on settings and feels like a tank too.
