Vitex is wonderful - it has helped me tremendously after coming off the pill - I have been taking it for only 5 days now, but for me i have felt the difference (maybe b/c i haven't really been eating for the past month - that also another awful side effect of coming off the pill) - i plan to take it for at least 3 months as the bottle says - i just wanted to offer this experience to some of you who may be looking into a natural relief of these awful panic attacks, depression, irritability etc - i am excited to see how i feel in a month! - please share your stories and symptoms, i would love to know just how many people feel like this and how many of your doctors did not tell you that this could happen - i think its terrible and there needs to be more research and pulblished research about the effects of taking synthetic hormones that supress your body - its unnatural and i would nver have taken it if i knew then what i know now
