What do dramatards do to say warm in Winter

I'm a cheapo and gas bills are still very expensive so I've been following the mantra of heating myself and not spaces.

Been wearing multiple layers of thermals including thermal long underwear and winter socks. Light exercise also increases the body temperature and reduces the need for so many layers for while. It's actually been far so far You barely notice the cold after a while and the only expense really is the hot water from the dishwasher and my shower. Been looking go renovate it be completely enclosed also to reduce moisture buildup and heat loss for less wasteful showers in future.

Going to bed with 4 big fluffy blankets also helps and the added weight strangely makes me feel very relaxed

Anyone here rich enough to burn a tanker of gas a week for home heating? !besties I've probably saved a few grand when the weather warms back up in February.
