I noticed it in my rent, which increased by $150 last month (honestly it's not that big of an increase, especially when it didn't go up last year), and my electricity bill in January, but since I've already lowered my consumption this fall/winter, it's still under last year's bills. Maybe I'll turn the thermostat down another degree or two.
As for groceries, I've decided to stop eating crap - because of inflation on my hips, not my wallet, so it helps keep it down. I mostly buy raw meat, milk, eggs and veggies. I did balk at the price of smoked salmon, which is one of my favorite treats, but it's now way over what I'm willing to pay (not to mention, I only buy wild, preferably Alaskan). So no more processed food, no more cheese, no more cold cuts, and unfortunately no more smoked salmon. My grocery bill is actually lower than it was before I started my diet - for more food, and I feel so much better too.
One thing that hurts is coffee. I guess I really need to use my French Press more often, but it's apparently too much of a hassle lol. Maybe I need a bigger one.
I don't drive much, so gas prices don't really impact my budget.
The rest of it, well, I just try to be more intentional when I buy something, and I just bite the bullet. As someone else said, not much fat to trim in the budget.
