When you clean your atomizers, usually a simple blow out should be fine. Just blow through the atomizer itself and that'll get it back going if it's gunked up and stuff.
As for an atomizer that has been ran dry multiple times and you've burned the wick, might as well trash it if you don't want to get into anything extensive like dewicking.
Getting used to e-cigs shouldn't be much of a problem as I've seen many make the change easily. You're still getting the nicotine, you just need to face that you'll need to detach yourself from the actual knowing.
You may tend to have a few small issues such as having a ugh feeling due to getting away from the other chemicals in analog cigaettes that you've also become addicted to that e-cigs don't contain.
If you're having a few problems at first, it's fine. Not everyones experience at first is perfect. It's all about learning and just going with it. No matter how many of these small problems you might have (which is common for noobs), it is nothing compared to living a much healthier lifestyle for not only yourself but for your family as well.
Enjoy and don't give up. vape on!
