Oh phew! Not sure which has been more of a relief... knowing that I'm not the only (once but def. would repeat if nec.) potette user OR doing the wee in the first place! Was either potette or bust at the time.
As for quantities (gross alert): I filled the bag. Could barely tie it. And I use compost bags as cheaper and don't leak. My husband, strangely, didn't want to look at it as I brandished it before him in shock (mega amount of wee) and amazement/ pride. Bit like my reaction to having seen my placenta fill the bowl - horror and amazement.
Please excuse disgusting-ness. Don't know what's come over me. Will pull self together.
