I have been taking Metronidazole for 10 days 500mg 3 times a day for a bacteria in my colon and in all honesty i have the metallic taste in my mouth , nausea , headaches , and cannot get erect.. I think it has affected me sexually because i am taking so much of it..This is the worst medication i have ever been on.
