I just took a tab that my dad gave me for my cramps & keep in mind that I never take pills that aren't given to me by a doctor but I feel so much better now. I was in tears from my period, the cramps were hurting so much & this is my first one in almost 4 months due to my birth control stopping them. I feel light headed but I'm glad the pain is gone.
