I was taking 1-2 tablets of a generic brand of Sudafed for the past year to control sinus headaches. It seemed to be the only product that worked! My outcome was a severe lack of libido. Zilch..nil. I didn't even want to be hugged or touched. At 45 yrs old, my husband thought our marriage was over and began surfing the internet until he found what he wanted. I have not taken even 1 tablet since Oct. and all the libido issues are gone. I just control the headaches now with ibuprofen and rest. The marriage is in repairs now that he knows it wasn't him!
