I took both Zyrtec and Benedryl as O approached, and though it might have made the EWCM driy of very, very slightly...it didn't really make a huge difference. I say try benedryl and see what happens. Take it only at night, though - it knocks you out! We ended up BDing 6 nights in a row, and by the end we were both so tired of the nightly routine and ready for a break!
