Comfortable room temperatures. Adjust your room lighting to your needs. Relaxation techiniques which can include, meditation or tapes. Comfortable layered blankets so they can be removed or added as need. Loose fitting bed clothing.
Proper support pillows for neck legs and arms if needed.
Proper bed material, I prefer a heated bed myself. Less caffine, sugar and nicotine in your diet. Most importantly if a tv makes you sleep use it. Most doctors will advise against this. What I have found is that most Fibros as I call us all seem to have a problem turning off their worry centers at night.
