Hi poindxtr,
The first year is typically the hardest, both physically and emotionally, because you're unprepared to deal/cope with it. It's a whole new learning curve for you body and your emotions.
I personally tend to get about 3-6 OBs per year, but my lifestyle, stress level, health status, hormone levels and supplement intake can make a difference. If I'm run down or highly stressed or sick, I'm much more prone to getting an OB.
I've also found that the times when I've taken a supplement called SAMe, I'll break out like clockwork. It's an alternative supplement used for arthritis and depression and it works very well for the latter for me, but at a steep price.

I've never heard of anyone else who has that reaction with it.
It's fairly common for women to get an OB just before or during their period. I've never heard an explanation as to why this is, although I know that my system tends to feel weak around that time. If I'm fighting a flu, I'll often come down with it at that time. Likewise with an OB, so maybe the immune system does a hiccup or something. *shrug*
I hope that helps, even a bit.
