I know where you are coming from Fairie - we are also renovating the kitchen and have been for 3 weeks now - OH is making the cabinets and renovating the old ones - but it is the MESS that is getting to me. Oh is doing it all the quickest he can but the kitchen and dining room is one room and it is very big!
We are also living off BBQ's and that's ok for me but as I have been sanding back doors etc I have not had any energy left to work out as such. My shoulders feel like they have become dislodges from my neck
So I know how you feel as I am going through the same sort of thing.
This morning I am going to jump in the shower (at least that room is not dust filled) and jump in the car and go shopping, even if it is for a few hours and BuG#er the kitchen
Hope it all sorts out for you soon...
