Gosh the constipation was horrific, nobody warned me!
Make sure to air the wound regularly. After a week I started to bathe it in cooled boiled salt water and let it dry out. Use clean cotton wool for each section of the wound. Shower every day and let the soapy water just run over the wound, make sure it's fully dry before dressing (don't use a towel on it though - just let it air dry).
My DH set up a pulley by tying together dressing gown cords together and tying them to the end of the bed so I could pull myself from lying to sitting. Awesome tip given to us by a friend.
Yy to keeping on top of painkillers, take as many as you're safely allowed and keep doing it, there's no point waiting until it hurts.
Go upstairs sideways.
Sleep with a towel under your knees, I found sleeping on my back after months of sleeping on my side so hard to get used to, but sleeping on my side would have hurt like fuck.
Loose clothing.
Last but not least, hold your wound every time you laugh, go carefully with coughing and for the love of god don't sneeze for a week or two!
Good luck, you'll be amazed at how quickly you start to feel better! I've done birth both ways and healed after section far quicker than the other way.
