Prevent? No ... lower, possibly but to what extent I dont know. but I can tell you I've never drank more in my life then the 4 years I was in college, I've also never been leaner, or made more strength gains then in those years.
I don't do this for my family, my friends, women, accolades, pride, or ego. I do it for me and no one else, its just part of who I am.
