IF I wanted to to get off nicotine, then I would want to combine the reduction in nic strength with strategies to prevent increased juice consumption.
I would probably want to reduce the power I vaped at. I would probably want to move to kit where I could easily track my juice consumption.
Perhaps using a tank that only contains a days worth of vape. Many of us probably controlled our smoking to some extent by seeing how many cigs were left in the packet compared to how long the pack was expected to last.
It is easy to reduce the nic strength and just vape more juice.
If you limit yourself to one fill per day it might be easier to guard against this. It might encourage you to start vaping later in the day, or to take longer breaks. Combined with gradual reduction in nic strength This should help IF you really want to break the nic habit.
Your mention of your husbands attitude , makes me think that perhaps you are not quite ready to give up for yourself.
You have made a big step to a much healthier life by stopping smoking. Your husband should recognise and support this.
If you want to take a further step towards becoming nic free then he should support that when you are ready.
Are you ready? Is that what you want, now? These are the most important questions.
If you really want it, you can do it. Decide on a strategy and a timescale and go for it.
