I've been posting about this a lot, like a new religious convert...but maybe what you're missing from vaping are Whole tobacco Alkaloids? I started a thread which is currently on the front page of this forum.
I'm not saying that's what you really need, but maybe it is. I found that it killed all of my cravings, and eliminated the need for willpower. I liked (like?) smoking, though, and for me to switch, it would have to be completely painless. With WTA, it is.
If you buy from any of the three available vendors, it should be simple to dilute some unflavored down to 6 mg with VG/PG and add 10% to your favorite juice.
If flavor's your issue, you might want to order some juices with extra flavor shots. For a juice without extra flavor added, I find Boba's Bounty to be nice and strong- if you like the flavor. it's not for everyone.
Good luck.
picked up
Mothers Milk
Peaches and Cream
Pumpkin Pie with Vanilla Bean at the B&M today, and had them double their strongest flavor.
Bought a 10 mil bottle and use that to dial in the flavor I wanted, and once they had it, I had them make me a 30 mil bottle.
Unfortunately I live too far away from the B&M to make it a daily visit, so I always buy extra of what I find I like.
Still trying but also doing it on a budget as well.
