Your neck pain may very well be caused by something simple...like the need for a new pillow. Also, what about your mattress? If it's old and saggy, it wil almost certainly cause problems. Basically your neck and spine should be supported in a straight position when you sleep, no matter which position you choose. If your pillow causes your neck to kink, you will have problems in the morning.

Next, take an honest look at your diet and exercise. You really need at least 30 min. Of excercise three times a week, or more. The exercise should increase you heart rate to a number that is equal to 200 minus your age. For general purposes, brisk walking is fine. If you can't do 30 minutes do 20, or 15 or whatever... Then gradually increase. You need to start somewhere.

Next, look at your diet. Get rid of the junk food. Get rid of sugar, flour, bread, grains. Focus on protein, non-starchy vegetables and a few fruits...like apples or melon. Avoid fruit juice.

Improving your diet, by itself, will make you feel better in a few days. Start adding the exercise and you'll be a new person by spring.

Good luck to you.
