IMO - Don't
Here is my suggestion. Like everything here it is all opinion.
Get a Eleaf IJUST2 battery only

Get a Starre Tank (NOT THE NEW STARRE PRO) - You can adjust the air flow up or down but later on you will find it was a good investment of many tank I already replaced with it early on (like Subtank, Herakles, Aspire, Artic). This tank loves a 70VG or higher VG mix, but you can use 50PG/50VG juice if you want. Many juice are.

Try stout liquid like "Holy Grail" from VaporBeast @ 24 nic level. Some folks feel this is the closest thing to a cig, no flavor.

Also try a stout flavlor-less mix with 24 nic (trust me)
Flavorless E-Juice
The hardware I stated could be had for not too much more than "kit". I smoked like you, I wish I had this set up the month I tried to quit the 1st time vs. the 2 EVOD kits.
Good luck and welcome!!!!!!!!!! We want you to stop smoking
As it was said it is totally normal to do both but get good equipment so you stand a better chance.
