I am going through the exact same thing, although I haven't wrapped. Yet. Due to not being able to find nice wrapping paper. Very annoying.
But I have a huge cupboard FULL to bursting with presents, I was going to try to go through them all, opened the door and thought "sod that till I get some paper" and left them ! I do have a list of things still to get, but I keep adding things to it, as I'm sure I haven't got enough !
I sort of remember what I've bought, the 'main' presents and things, but I keep seeing things and thinking of things and thinking "ooh, DS/DD would LOVE them/that".......
I just know when I do my 'last present shop' on Friday, come Saturday when I am ONLY supposed to be getting any food that I couldn't the night before at a mahoosive supermarket, I will end up getting MORE presents in a wildly abandoned "because it's Christmas" way. 
Not as painful to think about then !
