    Does anybody else find it odd that she takes codeine during the event?

      Hey Derek, here's her take on that: Codeine is a strong painkiller and it slows down gut motility… However, I stated clearly that i only use a tiny amount as it can cause drowsiness in some. It is not a prohibited substance.
