I am so tired this morning I could cry, I haven't had a night like last night since I was jet lagged. I fell asleep last night at about half 9, and then woke up at about 11,20, and I have been unsuccessful in falling back to sleep! I've never been a good sleeper but I usually manage to sleep until about 4am. I have no trouble falling asleep initially, it's just the waking up early and trying to go back to sleep. I've tried everything, reading a book, watching TV, a warm decaffeinated drink, an eye mask and ear plugs but nothing is working. When I wake up, and try to get back to sleep I can feel my heart racing, I try doing breathing exercises but they don't work. I've woken up in a foul mood this morning, and I don't know how I'm going to be able to sit through my childcare lesson from 9-3,30!
