I have been here at Halley for over 2 weeks now... and once again as per the last two trips I have a sleep problem.
24 hour sunlight & a reluctancy to waste a second of my time equals a lack of good shut eye. Hopefully then this bedside reading will help send me to Planet Z and then at the very least it will be my snoring that keeps the rest of my pit-room awake and not the seasonal abundance of Vitamin D!
