I think vaping is a great substitute for eating and drinking junk food/drinks, even for a non-smoker. Although I was a smoker, I plan on continuing with vaping once I get my nic down to 0 because I think the sweet juices will continue to help me as a substitute for sweets. However, I do agree with some of the others that you should up your water intake. Shoot for half of your body weight in ounces every day. That's what all the experts recommend.
