I can understand the hassle of having to deal with vaping, carrying liquid and other supplies, and making sure there's a charged battery supply handy. It's all part of vaping. I'm assuming that you are working and having to deal with this, especially since you mentioned a 4 hour commute.
For me, it's something I started right after early retirement, so I'm around the house enough to take care of the overhead. When I go out, I fill my 4.5ml Kayfun and grab a battery box with a spare 18650 and a filled carto just in case I break the Kayfun or the coil pops.
No matter what your age, going back to smoking increases the chances of developing Emphysema, Cancer, COPD, or any of the other health hazards associated with inhaling tobacco. That, in itself would keep me vaping.
So what you need is a good vape that doesn't leak, is easy to fill, lasts a while without constant refilling, and you can carry in a pocket. I'm thinking Smoktech Cartos (without the tank). I keep those around and find them to be a fairly easy draw. When I vape one of those, I usually chuck it after a day or two. You still have to top off or change to a fresh one, but if you use the cap fill method it's easy to fill several at night and keep them in a snap top battery box for a quick change when necessary.
