I have to say, nicotine is nicotine. I vape at 24mg. However, my house does not smell like cigarettes. Neither does my clothes, hair, breath, etc.
I still do an analog or 2 a day (perhaps I'm addicted to something other than the nicotine in the analogs - YIKES!).
I've only been vaping a little over a month.
Sort of off topic, but I vaped for about 2 months before I quit smoking. Before I started vaping, I had smoked 3 packs a day. I didn't rush to switch, but once I was convinced that vaping was a viable alternative, I did work at it a bit. When I got down to "a few cigs a day", it would be 5 on a good day, 10 average, 15 at most. Mostly I would get cravings after eating, and it would take 2-3 cigs to get rid of the craving. Vaping didn't seem to make those cravings go away.
I, like you, was using 24mg juice. I thought that was a pretty high level, and I really didn't want to move to a higher nic juice. (Plus, my favorite juice is Boba's Bounty, and like many places, 24 is the highest level they make.)
Eventually, based on advice from here on ECF, I ordered some juice in a 30mg level, small bottles, a couple of different flavors. I'd eat, I'd get a craving, and I'd use the 30mg juice via dripping. I continued to use the 24 as my all day vape, but I'd plan to drip into an atomizer with the 30mg juice after meals.
The day I started using the 30mg, I stopped smoking. I didn't even plan to, it just happened. I still had a half of a pack open, and 6 packs from the last carton I bought. But once I started dripping the 30mg, it was just easy to quit. No pain, big gain.
After the first week or so, I didn't use the 30mg a lot. I still have it, and on occasion I'll feel a craving and use it, but mostly I just needed it to get off the cigs, and the 24mg works fine for me most of the time.
Your story sounded similar to mine. You started vaping, you cut way down, but you're still needing a few cigs a day. You might try the system I used, get a some higher nic juice, and just use it to deal with cravings. Worked for me. I figure if I never use all the 30mg juice, I'll get some juice in a lower level and mix it. Equal amounts of 30 and 18 mixed give you 24mg juice. For now, I'm keeping it around for the occasional craving.
Good luck.
