I started with 18mg then went to 24mg which is fine for me. I think people who want to wean down to 0mg need to really question why they want to do this. There are huge health benefits in vaping comapared to smoking, but there is no additional health benefit in being nicotine-free. Being nicotine free can in fact be a very bad idea for many people.
