I, moved to diet soda to cut some weight and found that my sex drive was cut instead!!! It took me awhile to figure this one out, but I noticed I normally have a slight sciatic pain in my left leg, not much but just noticable. This went away and I noticed a slight numbness on the skin of my left thigh. All the while my libido was spiraling into nothingness. I finally realized that this all started when I moved to Aspartame sweetened soda pop. I noticed on the main page that impotence and loss of sex drive/libido was not mentioned, so I thought if this could help anyone out there please be advised. This is interesting too, because the new drugs for E.D.,(Erectile Disfunction) have become very popular. I tried a hand out from my Dr. and it worked fine, but if you can avoid taking any prescription drugs your life will be more enhanced. It seems like for every problem they will have a drug that will not cure the problem, but instead mask the symptom!!!!
