Since my husband returned from a week's respite care his sleep pattern has altered dramatically. Whereas he was sleeping from 15-18 hours a day, he now doesn't go to bed until about midnight and is waking up at 5am. He follows me around all the time, asking me what he's doing and wanting constant hugs. He is still crying on and off. I realise this is probably caused by anxiety and I have booked a face to face in a couple of weeks time with the GP to discuss medication, but wondered whether anyone else had experienced such a change. It's causing me such stress that I can feel everything bottling up inside me.
