While I agree with some of the comments, I also don't agree with some.
Everyone and I mean everyone that vapes has gone through the same thing as yourself. Coils that didn't work tasted like the back end of a cat, juice tasting like it was burnt. There is a learning curve to this. There are a ton of people here that have gone through the same thing as yourself. Some of us have waddled through on our own and some of us have sought out help one way or another.
Like everyone else, I started out on the skinny auto types and found out real quick they were not going to work for me. So I graduated to an ego. From there to a Vmax, Gripper, Vmao and a Sigelei Zmaz and a Tec mechanical for my RBAs. Right now I'm waiting on my Groove to arrive.
I also make my own juice and that was a heck of a learning curve. But I keep up with it and now I have 6 juices I call my own that I enjoy everyday.
The main thing to remember is, vaping is not perfect, you're not going to get the same type of hit or satisfaction as an analog. But try to remember how it was when you first started smoking, took you some time to get use to it, didn't it? Same thing with vaping. Keep with it, ask a ton of questions. The only dumb question is one that is not asked. You'll find a wealth of help and advice.
