Well, my first few days went pretty well. I ended up needing to take an Uber home from the airport, which is a facepunch, but covered the expense with some gifted holiday money so I'm considering it my one treat for the month. I also pulled off a $30 grocery shop for the week and have bulk cooked a few soups to freeze.
But then we got our December gas bill (heat, stove)! It is $220 (November was only $80). I'm totally bummed... we have well sealed windows, live in a small single floor middle unit apartment, and keep the heat between 58 and 68 depending on the time of day. When we called, the gas company said that the previous tenants had a similar bill for December. Now, I live in a cold and expensive city, but all my previous houses and apartments here have been less well insulated but with a lower bill (for example, a huge creaky old 5 bedroom house was heated for about $160). The saddest part is that it has felt totally cold in the house for the past month.
We are considering drastically lowering our heat and using space heaters for the rooms we are in at that moment. On the bright side, at least by doing an uber frugal month will help offset these costs.
