I've taken metronidazole twice in the past year for intestinal parasite. 700 mg, 3x a day for ten days. I have an awful metallic taste in mouth, dark brown urine, lost of appetite, fatigue, and headaches. Some days are better than others. I have found that drinking beverages at room temp with out ice helps along with hot food. Something to do with the temp of the food brings out the metalic taste. I also chew gums and suck on peppermint candy to mask the taste.
