Drink you 2 tablespoons in a 8 oz glass of water.

That'll slow it on up.

Worked for me.

I was on a vinegar regimen like, daily. I used to suffer from 10 day stretches when my period decided it wanted to show up (I have PCOS). That vinegar cut them visits down to like, 5 days. I was still in the bathroom changing equipment every 2 hours and shit, but it shortened the duration and heaviness.
