Why is this? I just started drinking my morning midstream urine 3 days ago and I'm CONSTANTLY tired and hungry. Why? Has anyone else experienced this? Also, I have an Amalgam filling in my mouth and about three days ago, I started being able to taste the metal! Are these things related? Is there mercury in my pee? I'm getting my filling out in 2 weeks, and I don't want to be repoisoning myself if that is the case. Thanks for any help.
