What steps did you take to achieve this?
Prior to living at my current place, I lived in apartments where the heat was automatically included in the rent. I preferred keeping the temp at 75, but would compromise with roommates at 73. Once I got my condo and had to pay my heat for the first time, I "compromised" at 73 lol. Hence the huge bills. Also my bedroom was in the coldest room of the house. I found myself keeping it warmer in the rest of the house just so my room wasn't cold.
Luckily, after that winter I was able to switch bedrooms to a warmer room, which had a significant impact. The next winter I decided to buckle down thanks to reading this forum, and compromised further to 71 during the day, with 68 (maybe 66 at times?) during the night. This year I managed to bring it down to 70 during the times I'm home, and 63 during the day and at night. Huge difference! I also use an electric blanket at night, works like a charm. I would've even brought the day/night temps lower, however I have a sickly/elderly cat, and I feel like that would be bad for her.
