green output

     This morning my output was a dark green.  I could understand it if ate green vegetables yesterday, but I didn't eat anything green at all.  I did drink a few glasses of iced tea, but it wasn't green tea.  Could it be I am taking too much Tylenol?  My arthritis has been kicking up and the only thing I take is extra strength Tylenol, but only take one tablet per day.

If I have peppermint tea it sometimes goes green.

Also quite often in the morning I have a yellowy green output. If you hadn't eaten for a number of hours (i.e. you ate early before bed) it is more common to have yellowy / green output.

Yep. Sounds like bile.
