I like coffee with a lot of milk in it. Couple years ago I was farting so much it made me want to stick a cylinder in my ass so the gas could seep out on its own. I decided to try some fat burner capsules, and I decided that I would drink decaf coffee since they have caffeine. I only drank about half of it and poured it out, because the caps killed my appetite. The fart problem went away when I only drank half a cup of milky coffee. I had a short conversation with some guy in a coffee shop around that time, and he was telling me he was lactose intolerant. So one day it occurred to me that that might be my problem. I bought lactase tabs, and it made the farting go away.
