3 weeks into my latest cycle (2-3 years between them) I stumbled on to this thread, and since I'm not on any medication other than red bull I thought I would give licorice a try. After taking the amounts and frequency that Les suggested my CH were gone after about 7-10 days. The licorice root definitely worked for me, my cycles usually last 6-8 weeks so at the very least it cut it in half which is amazing. The thing i liked best is I didn't need a prescription for this, just pay $14 for the licorice root in a health food store. Thank you Les!
