Don't be hard on yourself. One day at a time. Personally from a 1 1/2 to 2 packs a day, I have cut down on cigs to about 6 per day and I've been vaping now for 3 plus weeks. I haven't found a good throat hit yet, as that is what I like about the cigs. It's all a learning curve.
I agree with the others on here, it does get better. I've noticed that I'm getting my taste buds back and can actually taste some of the flavors of juice that I got. I'm a menthol smoker, so got menthol crystals that I've added to my juices and wow! IT really did help to cut back on the cigs quite a bit. Like vaping vicks! LOL! Now I'm even cutting back on the menthol crystals I was adding so I can taste the other flavors.
Hang in there! Find the right stuff and vape away, and in no time, you'll be done with the cigs!
