I didn't go to the doctors to figure out if I'm lactose intolerant, but every time I drink milk I would have all the symptoms for it and end up on the toilet for a few hours. I wasn't lactose intolerant when I was younger though. However, the other day I went to Starbucks and got a Vanilla Creme, which is basically steamed milk with vanilla syrup ( I looked it up). However, that day I had no trouble drinking it and had none of the symptoms that usually appear. I was wondering, if that was just a fluke or maybe steamed milk is still okay for me to drink?
