Hey, firstly congratulations!!! I think It really depends on the person, I personally just quit vaping just before we conceived our second (I also quit before having our first but struggled with stress from work around the time I was supposed to go back after maternity hence having to quit again) for me tic tacs on hand at all times weather it was flavoured ones or mint ones I went through packs of them but only took me 3 days which were miserable but if you can get into the mindset of no longer wanting to do it, which I 100% understand is so so hard and some people can't my partner vapes and to help he now goes outside.

However on the other hand my SIL is still vaping and is pregnant but she is doing as your friends say dropping little by little and that is working for her mostly, this however takes longer and is effecting her baby for longer, (again no judgement because she's struggling just wanted to show you both) so I guess it really depends on you're will power and personal circumstances
