My mind was quite good throughout. I didn't feel grumpy. I tended to be a bit antisocial, partly because I didn't want to put myself in situations that were overly tempting, but also partly because I felt quite introspective and just didn't feel like socializing. I definitely felt like my mind was working faster than it does normally - I don't know if it was having a tantrum, but it was bouncing off the walls sometimes.
