It is hard to say what would make things more satisfying to you and get you over the hump. For me, I had to drop my nicotine strength and suck on the danged thing like a pacifier to keep me off the analogues. And I mean constantly, more than 7-8 ml of juice a day. My buddy needed higher watts for more heat, so variable volt fixed it for him. My sister had to switch from desert flavors to tobacco.
I haven't tried WTA, but before I got over my hump that was the way I was leaning.
The only thing I can really suggest is to try to see if it is something besides the nicotine you are craving. There is so much more to this addiction than just that. It can be social, or flavor, our the physical hand to mouth act, or going outside.
Good luck.
