So I haven't slept more than a couple of hours at a time lately and I am surprisingly feeling good and have not yet fallen over. I am reminded of links between 'excess' sleep and depression, though I am not trying to imply and particular causality here (nor were they).
I am definitely less coherent, and as I tire I get slower and slower. I still wake before my alarm though, and for the most part my spiralling over-analysis is replaced by a shimmering awareness of the present. I feel *here*. Not, I suppose, that I have time to worry lately.
