Bear with me, I found this online and it seems relevant to everyone here, it is somewhat large in nature.

Sleep and Posttraumatic Stress Disorder (PTSD)

Pamela Swales, Ph.D. and Jessica Hamblen, Ph.D.
Many people have trouble sleeping sometimes. This is even more likely if you have PTSD. Having trouble sleeping and nightmares are two symptoms of PTSD.

Why do people with PTSD have sleep problems?
There are many reasons why people with PTSD may have trouble sleeping:

Changes in your brain:
PTSD can cause changes in the brain making it difficult to sleep. Many people with PTSD may feel they need to be on guard or "on the lookout," to protect him or herself from danger. It is difficult to have restful sleep when you feel the need to be always alert.

Medical Problems:
There are medical problems that are commonly found in people with PTSD such as chronic pain, stomach problems, and pelvic-area problems in women. They physical problems can make going to sleep difficult.

Your Thoughts:
Your thoughts can make it difficult to fall asleep. People with PTSD often worry about general problems or worry that they are in danger. If you have not been able to sleep for several nights (or even weeks), you may start to worry that you won't be able to fall asleep. These thoughts can keep you awake.

Drugs or Alcohol:
Some people with PTSD use drugs or alcohol to help them cope with their symptoms. Drinking and using drugs can make it more difficult to fall asleep.

Upsetting Dreams or Nightmares:
Nightmares are common for people with PTSD. Nightmares can wake you up in the middle of the night, making your sleep less restful. Or, you may find it difficult to fall asleep because you are afraid you might have a nightmare.

Hearing a Noise:
Many people with PTSD wake up easily if they hear a noise. You may feel that you need to get up and check your room to make sure you are safe.

What can you do if you have problems?
Whatever the cause, there are things you can do:

Your sleeping area
Your sleeping area and what you do during the day can affect how well you sleep. Too much noise, light, or activity in your bedroom can make sleeping harder. Creating a quiet, comfortable sleeping area can help. Here are some things you can do to sleep better:

• Use your bedroom only for sleeping and sex
• Move the TV and radio out of your bedroom.
• Keep your bedroom quiet, dark, and cool. Use curtains or blinds to block out light. Consider using soothing music or a "white noise" machine to block out noise.

Your evening and bedtime routine
Having an evening routine and a set bedtime will help your body get used to a sleeping schedule. You may want to ask others in your household to help you with your routine.

• Don't do stressful or energizing things in the evening
• Create a relaxing bedtime routine. You might want to take a warm shower or bath, listen to soothing music, or drink a cup of noncaffeinated tea
• Go to bed at the same time every night. And get up at the same time every morning, even if you feel tired
• Use a sleep mask and earplugs, if light and noise bother you.

If you can't sleep

• Imagine yourself in a peaceful, pleasant scene. Focus on the details and feelings of being in a place that is relaxing
• Get up and do a quiet or boring activity until you feel sleepy
• Don't drink any liquids after 6 p.m. if you wake up often because you have to go to the bathroom.

Your activities during the day
Your habits and activities can affect how well you sleep. Here are some tips:

• Exercise during the day. Don't exercise after 5 p.m. because it may be harder to fall asleep
• Get outside during daylight hours. Spending time in sunlight helps to reset your body's sleep and wake cycles
• Don't drink or eat anything that has caffeine in it, such as coffee, tea, cola, and chocolate
• Don't drink alcohol before bedtime. Alcohol can cause you to wake up more often during the night
• Don't smoke or use tobacco, especially in the evening. Nicotine can keep you awake
• Don't take naps during the day, especially close to bedtime.
• Don't take medicine that may keep you awake, or make you feel hyper or energized, right before bed. Your doctor can tell you if your medicine may do this and if you can take it earlier in the day.

Talk to your doctor
If you can't sleep because you are in great pain or have an injury, you often feel anxious at night, or you often have bad dreams or nightmares, talk to your doctor.
There are a number of medications that are helpful for sleep problems in PTSD. Depending on your sleep symptoms and other factors, your doctor may prescribe some medication for you. There are also other skills you can learn to help improve your sleep.
