I also appreciate the input guys.... I started taking 20,000IU a day, only a few days ago, and I have seen an improvement in energy levels and overall feeling of "wellness" already. It will take a little longer to see if it has an impact on DUB. I have an appointment with OBGYN in 3 weeks to schedule a D&C. I am hoping that the vitamin A will have had enough of an impact, that it may not be necessary anymore.
