Query: Didn't work and side effects...

I read through many reviews searching for the right type of herbal pill and finally settled on Breast Actives. When I got it in the mail I was so excited, I started taking the pills that day. After a couple of weeks I noticed NO gain in bust size (I was measuring), NO tingle that many of the other reviewers claimed indicated the product was working, and horrible, painful gas and bloating. In addition, the cream smells just like cocoa butter. Not worth the money. DIDN'T WORK.Breast Actives 1 KIT Breast Enhancement Kit by Breast Gain Plus 1 - 60 Tablet Bottle and 1 - 2 fl Oz Jar of Cream
