I am planning on ordering a small bottle of this soon to have with my supplies, but thought I'd ask for experiences first. I've heard nothing but good things about it...did anyone think it didn't help at all?? Any suggestions on the least expensive place to order from? (or any with free shipping on low totals?) Also, I was wondering, is this something that would help for AF cramps? I get nearly debilitating cramps with my cycle and would love to forego the ibuprofen.
