I can tell you have not found your juice yet. It wasn't until I found a juice that would work for me that I knew I could stop smoking. And even after finding that first juice it took time.
It took two things for me.
First, discovering just exactly how utterly delicious vanilla is. I'll try anything, and I'll even use crap I don't like much because I hate to waste, but when I want a good, solid vape, one that I'll really enjoy...it's vanilla every time. This really helped a lot. I'd so way rather have a vanilla vape than a cigarette. The flavor just does something amazing to my brain.
When I'm in situations where I might be overly tempted to smoke, I always bring some vanilla juice with me. If I find myself about to bum a Camel from someone, I just vape a couple of drops of that instead and usually forget all about it by the time it's time to drip again.
Conversely, my first couple of tries with ejuice were all tobacco flavored. I finally realized that I was just holding on to something that I was also trying to let go of. Quitting with that stuff helped a lot, I think, but I can definitely see how the opposite would be true for some types. It's just better for me the less I'm reminded of smoking.
Second thing...don't buy cigarettes. Nicotine addiction is only a small part of the total smoking problem. The habit is huge. The idea of lighting a cig, feeling that first puff in your lungs, smelling the smoke...these are things that your body and mind associate with the relief of smoking when you need to. Vaping is close, but it doesn't fully emulate that sensation.
If you have cigarettes, you are going to smoke them. If you
don't, you're going to do the next best thing, which is vape. Vape your ... off, be stupid about it...drip a whole mil in one sitting if you want. When you do this, if you're using a juice you love like I love vanilla juice, it won't take long for that feeling of relief to reassociate with this new habit.
Also, I found dripping to be pretty analogous to lighting a cigarette...you get about one cig's worth of vaping out of the 2-3 drops you can fit in a 510 atty, and that helped a lot, too. Pull out the PV, the bottle, unscrew, drip-drip-drip, vape...same thing as pull out the cig pack, the lighter, take out a cig, light, smoke. But better.
