You can easily ween yourself off nicotine by mixing your own vape juice. Make small batches, lowering the nicotine % by an imperceptible amount each batch until it’s effectively 0%. Then keep vaping 0% until the urge goes away. Do it over the course of a year, and you’ll never notice the drop. No willpower needed.
