I use to kill milk. Seriously would drink it like water. During a diet one year, I cut it out totally. God I missed it. After about 5 months of not having it, i started drinking it again. The first night I had it, I woke up with mucus in my throat, like, a lot. Didn't think anything of it(reguarding the milk) Second night, same thing. I was like, I'm not sick, so what's the deal. Dawned on me, maybe it's the milk. Stopped drinking it, it went away. Tried drinking it again, mucus city. Concluding, my body somehow developed and allergy to it. What a bummer. Nothing like peanut butter and jelly sandwich with a glass of milk. My life is over
