"been a great pill for me. got turned on to it after using the &quot;4 period a year&quot; method. that did not work well for me and really upset my body chemistry. after about a year or two without taking any pills i started using levora. no side effects whatsoever and i feel better on it than i did when not using the pill at all! it levels out my hormones nicely i think. but as with any medication, you have to find a pill that works well with your chemistry."
