small, round, green pill with P on one side, O-M on other
Hello, could somebody help me identify this pill? It is a small (about 5mm diameter), round lightish green (or maybe blue?) pill. It is not scored; one side says "P" and the other says either "O-M" or "W-O".
If helpful, here is a blurry cellphone picture of the pill in question:
