Adventures with zinc and fighting menstrual evils

So I start my period in four days. And thus, I start taking zinc today. According to various things I've been reading online, I can all but avoid the evil painful cramps I generally have by taking 30-90 mg of zing starting a few days before my period begins. The unfortunate side effect of this is the nausea. I just took a pill not too long ago, and my stomach is already churning and I kinda want to throw up. Ah, zinc. However, if this works, having 15 minutes of nausea a few times a day for 3-4 days is significantly better then having 48 hours of incapacitating pain!
