I've been vaping for over 2 months now and have been lactose intolerant ever since I started smoking. Lately I've found myself able to eat dairy products again. I started with a couple slices of pizza near home just in case. No problem. Had pizza again the night after cause things taste better now. No problem again. Had a slice of birthday cake for my friend and no problem. At that point I decided to test it out over the weekend right by the throne just in case. I had a full bowl of cereal with just "normal" milk and waited... no problem!!!! Now I'm going crazy eating all the dessert I could never eat before, and putting milk and cream in everything like I used to. I literally used to drink a bag of milk a day when I was younger. Now I might start doing that again. lol. If anyone out there has lactose, test it out, you might find the same thing after about 1.5 months of vaping. Cheers!!!
