When I was off work ill for over a year, I ran out of sick pay and had no wages, so our income was drastically reduced, We had to rely on DH's occupational pension. (We have joint bank accounts and personal savings pots, which although we have access to in case either of us dies, we would never dream of looking at them.)
However, I wasn't driving, so no petrol needed, I wasn't being asked to donate very week to leaving gifts, birthdays etc. I wasn't going on expensive staff nights out and we certainly couldn't go on holiday.
Initially, I worried about how we would manage, especially as I was the main earner, but it is amazing what you can do, when you decide to curtail your spending.
It did open my eyes as to how much I had previously spent on things I didn't really need.
