Welcome and congratulations on making the right decision. It took me a couple of months before I quit analogues completely. The right equipment is everything. Everyone will have advice, but the thing about vaping is that it is very personal. Trial and error will eventually lead you to what is right for you. Don't go straight to advanced level stuff first, you need to see if vaping is going to satisfy you, and your experiences will aid you in keeping with it as you progress up. I use RBAs, mix my own liquid from 100mg nic, and use variables, and I even have a mechanical that I use infrequently. However, I started with the old 808 and carts, before the ego tanks were even available. As they came out, I pick some up and it just progressed from there. The thing is to keep at it because your health will improve, you will be able to taste things again, you will not cough, you will be able to run up stairs again and you can vape in your car and home and no one will know it. You will stop smelling like an ashtray.
I noticed all of these things right away, and it is wonderful. If you are having trouble at first with trying to stop the analogues altogether, then increase your nic. At one time I was feeling tired all the time, so I upped my nic to 35mg and wasn't tired any more, but I then started lowering it down. Try different combinations to see what works best, PG/VG percentages, VG will give more "smoke", but many swear that PG gives more flavor. I use 100%VG, have never had a problem, but if it is a bit thick for your atty, then add some DW. I use a little DW to thin a bit, but other than that, I am all VG and flavor is great but with huge plumes of vaper.
Remember, this is very personal and just because something isn't working for you but someone else raves about it, don't worry, just try something else. This forum is the best there is for help and advice. Some of us have been doing this for a long time and are always willing to help. Look around and you will learn a lot. There is a learning curve and there is also a cost curve. Equipment like batts and so on give an initially high cost, but once you get everything you need, it is always way cheaper than analogues. I have equipment that have lasted years and I still use it every day.
Good luck and again, congratulations.
