After years of suffering from long, heavy, periods, I mostly got rid of TOM. I take birth control pills daily for 3 months and then stop for a week. Only have to deal with about 3 days of spotting every 3 months. This has been one of the best things I've ever done for myself or that a doctor has ever suggested for me. TOM...an unpleasant, mostly unnecessary, inconvenience to be avoided as much as possible, in my opinion.
