I forgot about everything I had with me, DH was the one who shoved things at me now and again, it made him feel useful..
I did have the homeopathy kit, it was actually much more useful afterwards and during pregnancy. Forgot it at the time.
Water with rescue remedy in it, glucose tablets, 3 or 4 long tshirts (very long - amazing how they ride up), slippers (for afterwards). Hot water bottle fabulous in the early stages of labour. In fact, two - one for the front, one for the small of yr back. Felt sooo good!
Don't waste yr money on the paper knickers, get big granny pants, pref in a dark colour. They're cheaper long term, and black doesn't show anything. You'll only need to use them for a few weeks til you stop bleeding, then chuck 'em. Also come up v high, so good if you have an unplanned CS.
Love the recommendation about the Flash wipes (though also find it depressing). Sounds like a must to me, have heard horror stories about catching infections from dirty hospital baths.
If you're labouring at home, stay there as long as you can, then you can have all things to hand anyway.
Neal's Yard seaweed and arnica foam bath is the perfect present to yourself for a bath afterwards.
