I recycle as much as possible, not just the stuff you put out for the recycling collection but take stuff to the recycling bank that isn't collected like tetra packs.
Vegetarian and trying to cut down dairy.
Buy fruit and veg loose as much as possible.
I buy laundry detergent, washing up liquid, shampoo, conditioner, hand wash, cleaning stuff from the refillable section of our local Eco store, you can refill any old plastic bottles or containers, I have a shampoo bottle that's on it's 30th use.
I use the same store to buy lots of food staples such as pasta and rice loose (again you bring your own container) and often it works out cheaper than the equivalent in the supermarket.
I switched to loose leaf tea as most teabags contain plastic fibres.
I avoid palm oil as much as I possibly can.
Use toothpaste tablets instead of tubes.
Walk as much as possible.
Use beeswax wraps in packed lunches.
I make sure any wrapping paper I buy is the type that can go in the recycling.
Have a refillable coffee cup.
On my to do list is to try a mooncup or similar.
Most of these things I wouldn't even consider sacrifices though.
