I wonder whether anyone can help with the following problem ... A friend of mine has Parkinson's, and has very disturbed sleep every night. The symptoms are similar to 'freezing' (ie immobility) and this can happen anything up to 10 times in a single night. Does anyone have similar experiences, advice or suggestions on how to cope with this, or can anyone point me to any literature on this subject ? As you can imagine, lack of sleep can make it even harder to cope with the other symptoms of this disease, so I'd be very grateful for any help you could give. Many thanks, Dawn Witherden
