Cig a likes tend to be an expensive way to vape.
You'd be much better off / higher chance of success with a decent power device and a simple delivery device, like a Pico & Nautilus variant.
You're not of legal age in your state so I understand the need for something easy to conceal.
But, IF, I could limit myself to 5 smokes per day with no desire to increase amount, I'd smoke, but, I can't, so I don't.

Probably due to not understanding the relationship between amount of cigarettes smoked and the appropriate nicotine level in e liquid used to mimic smoking intake of nic.
You are & have been using using nic levels that are way too strong for a 5 cig per day habit.
2 packs per day = 24mg/ml
1 pack per day = 12 - 16 mg/ml.
1/2 pack per day = 6 - 8 mg/ml.
5 cigs per day = 3 - 4 mg/ml.
Above are approximate / good starting point.
Use of sub ohm resistances, cut above in half to start.
If all you smoke is 5 per day, best bet is to reduce smoking 1 cig per week, in 5 weeks you'll be free of them.
