I just went through the same thing. I didn't worry about it as I had seen the problem posted before. It lasted about 4-5 days & now it's gone. I've also been peeing caramel, chartreuse, and a NEW color, let's call it "desert sunset"...kind of orangey. This has all happened since I've upped to 31.25 mg. per day..... I guess we're starting to move them poisons out! :)
