I'd give licorice tea a start for 3 weeks or so. Monitor your own blood pressure.
I used licorice and cayenne and later lobelia. You can get licorice from http://return.to/organicherbs herbs and cayenne, lobelia, 'heal herbal thyroid', Hormonal Changease from http://superfood.andmuchmore.com/
I do echinacea for the first 2 days of every month.
Diet is key. But I need to know where you are to proceed.
