I cut coffee out a few months ago & only drink the odd cup of tea now but apparently you have to be careful with that as well (and cola drinks). I used to be addicted to coffee and went off it cold turkey. I did not get headaches or anything. It was incredibly hard to do as I kept having cravings for it.

I'm also trying to eliminate trans fats from my diet for the same reason but that's much harder than coffee as it's in so many things, and many companies don't list it on their products so you don't know it's in it.

The good news is that after cutting back majorly on caffeine and trans fats I fell pregnant very quickly (after many years of infertility). The baby did not stick so I will be doing my damndest to eliminate these things entirely from my diet now as I am thinking that my diet has been contributing to my problem for all these years.

Can't say I'd heard anything on low fat milk affecting fertility. I don't drink it these days but I used to religiously for years... perhaps that was an issue for me as well.
