Thanks to everyone for their comments. I've just managed to sort out all my clothes in my bedroom (they've all been in a big pile on the floor since I moved in) and am still just drinking water. Even cleaned the toilet - man was that overdue
Agree with something said above re tipping - if I want a bottle of wine I can just go buy another. If I do crack later, I don't think this will be because I did or didn't have a bottle in the house - has never been before. So God forbid, but if I do crack I'm just wasting money by tipping. Doesn't work for me.
Bedtime sure feels a long way off though.
