If you're having trouble falling asleep, try relaxation exercises. Learned a great one in third year from a class on "Body, Mind and Spirit."
Lie on your back and take three very slow deep breaths. Then start thinking about relaxing one part of your body at a time.
Start with your toes, think only of relaxing your toes and say slowly, "toes, relax; toes, relax; toes relax, and they are so relaxed." Think next of your feet, and say, "feet relax; feet relax; feet, relax, and they are so relaxed." Repeat this pattern "x relax; x relax; x relax, and they are so relaxed" as you move up your body: ankles, calves, knees, thighs, hips, stomach, back, shoulder, chest, arms, elbows, wrists, finger and finally your head. Push all other thoughts out of your mind, concentrate only on that one part of your body, on relaxing that one place, letting the tension drain.
If you're still awake (I personally never make past my hips when doing this exercise), keep your eyes closed and envision lying on a beach, hearing only the gentle sound of waves; think of a colour, a warm soft colour and let it wash over your body, feel the tension drain away as the colour washes through you, keep adding a colour and let it wash over you - drive all thoughts but the sound of the water and the feel of the colour away from your mind. These are wonderful ways to relax, and if you're in bed, can really help you fall asleep.
The key is to think only of the single object, let no other thoughts, sights or sound intrude. I know it sounds all (old) new agey, but it works.
Xita, DMW, have you tried sleeping with a pillow between your knees? It takes a little getting used to, but a small flat pillow is helpful when you sleep as it assists in keeping your spine aligned, which can take some of the pressure off other areas (hips and back especially).
Hey DMW, right there with you girl - adds an entirely new meaning to a book's "impact", and a new understanding of how a book can truely leave it's mark.
Cheers!!
