I guess I'm going against the grain here, but I started at 24mg some six years ago, and I'm still using 24mg today. Only difference is I mix my nic and flavors myself. I'm not at all looking to decrease either. What for? When I first started 24mg is what got me off a 45 year 3 PAD habit. Right from the first. Never looked back. So, I'm sticking with my 24. I don't see any harm whatsoever in it, I look at it as more akin to a caffeine habit, and that ain't going anywhere either!
Interesting thread.
