Just a thought, but it has been my experience that whenever you deny your body something that it is used to having, your body deals with it in very odd ways. That may be a reason for the menstrual cycle delays. Just your bodys way of saying "Hey where is that chemical I am used to having?". I truely hope that you are able to stay narcotic free. You have actually given me some hope, just reading your random posts. Thanks and good luck.
