A cool dark room is a must to getting a good nights rest. Most medications that are taken at night also assist in knocking you down, relaxing the mind to ensure a restful sleep. Just ONE night with a disturbed sleep can have you spiralling out of control. You may need to increase meds to alleviate this issue. I find either reading or watching television in a lounge room with dimmed lights or even candles assist to wind down an overactive mind and prepare myself for a night of blissful slumber.
