Vaping while pregnant

Recently i have found out i was pregnant & ive been vaping.. i have been for 4 years.. so its kinda hard to completely stop vaping after so long of doing it.. A lot of people say that their obgyn recommend that you vape instead of actually smoking a cigarette. I dont vape as much as i use to now since finding out, but soon i want to come to a complete end to it, but i dont know how.. people say to eat sunflower seeds, chew gum.. ect. I just dont want to be stressed from not having nicotine. 😣
