I just asked my Mrs and my sister this question and I didn't think I had but they said there's a few small differences, apparently my tempers a lot shorter than it was and I'm kind of aware of that and for me I put it down to frustration because just small things like sometimes needing help say just putting my shirt on drives me insane, I'm a 34 year old man that's been fircely inderpendant since I was 15 but now needs help dressing ones self so I do lash out sometimes not meaning to, there's a few other things but nothing major. One thing from me though is I've lost my sense of smell and taste after having people messing about in the brain.
