It's quite an adjustment being back at work.
I found shopping this Saturday to be a quite an experience- the shops were packed, when I was at home I would go in the week. I spent quite a bit, but I have got the bulk of the shopping done till at least mid December- so that helps.
I am taking my own lunch most days of the week- I either make extra when cooking supper, or pack some salad, tuna etc and make my sandwiches with rolls from the bakery. I prefer to treat myself to something I really enjoy ( like a falafel)once a week, rather than buy a boring sandwich everyday
I don't have to wear suits or heels to work, as long as I look respectable( to quote my boss). I've started getting to get into the habit of changing when I get back from work, means the clothes last longer and I'm more comfortable at home
