I stopped drinking milk because of all the hormones and chemicals they pump into it. I was younger and didn't realize that milk was in fact causing all my acne. I broke out all the time during my teen years, and milk was a huge factor as to why. I've stopped drinking it, and it's gotten much better.
I had spots too and I drank a lot of milk.
But when I stopped worrying about my spots they actually went (I got my first GF and I stopped caring). I still drink lots of milk so I don't buy it.
