I know I'm supposed to stop taking Vitex and Saw Palmetto after I O, but should I take my regular doses on O-day? I'm due to O sometime today (I think in the afternoon), and I normally take my Vitex and SP around noon. Should I still take it? What about antihistamines? I normally take my Zyrtec at suppertime, but should I pop a Benedryl at noon before I O?
