I started with a triple battery regulated mod and a 25mm RDA with a pair of handbuilt Ni80 fused clapton coils at 80 watts, and, I got into complex coil building within only weeks after. But vaping instead of smoking does take some getting used to, despite it didn't make me cough. Using a regulated mod for this abrupt change was a smart move for a variety of reasons. Jumping head first into unregulated or mech would have simply been too much for me to learn at once. Instead, I was focussing on learning first things first: to not overdrip, to not get dry hits, to vape long enough beforehand as to avoid cravings, to count drops of nic-free juice straight on top of the coils after dripping the 6mg always first as to kill the harshness from the juice containing too much nic─especially the first couple of hits in the morning were harsh as if part of the nic had risen up into the coils overnight─as well as to temporarily lower the nic strength to be able to continue to chain vape and not get nic sick as a result, and to properly rewick an RDA, and and and...
Thing is, I never was a dual user so I managed to completely avoid the struggle commonly associated with smoking normal cigarettes between vaping sessions. Immediately from the get go, I knew that not everyone is capable to do the same, but I also had a gut feeling that one major important reason why I did succeed at skipping the gradual transition stage from smoking to not smoking was because I made the right choice with what appeared to me like an excellent way to start. I never could get a satisfying vape out of a low or medium powered setup. This, then, confirms that my choice for me was right. I got my first mech within only some months after, and, I haven't vaped on a regulated mod in a long while. I am certain that I could teach someone how to start with a mech right off the bat, if this someone had the patience, handiness, sense of responsibility, and willingness to learn. But I didn't have the privilege of receiving that much help when I started. Else, knowing what I know now, I would definitely have chosen a mech to start. Then again, you don't know something until you know, so... not sure how I could have felt confident enough about the competence of my teacher if there had been such a teacher available. Having to teach most of it to myself was pretty much inevitable because the knowledge that I know now doesn't exactly come falling off a tree. At least not IME, unfortunately, it didn't.
