Inability to sleep, also known as insomnia is very common in pregnancy. It is felt by some to be nature’s way to help you get accustomed to the lack of sleep you will experience after your baby is born!
Insomnia is mostly due to the high estrogen from your pregnancy. The high estrogen of pregnancy acts like caffeine and is a stimulant. It feels as if you have had a cup of coffee right before going to bed. You will often fall asleep but wake up soon thereafter and not be able to fall asleep again. A frequent need to urinate as well as difficulties finding a comfortable position in bed usually just add to the problem.
If you experience problems with your sleep, the best thing to do is to take a warm shower and drink a glass of warm milk before bed. This will relax you. Make sure your bedroom is not too warm and allow for a lot of pillows in your bed to help make yourself feel more comfortable as well. If you wake up, instead of tossing and turning in bed, it is usually best to get up and do something such as reading. Avoid the television, smartphones, and tablets as these will inhibit your ability to fall asleep again. Try to only return to bed when you start feeling sleepy.
You can safely take 250 mg of Magnesium or 25 mg of Diphenhydramine (Benadryl®) before bed to help you fall asleep. If your insomnia is very bad and you are very exhausted, some medical health providers will prescribe an effective prescription sleep aid called Zolpidem (Ambien®) that you can take occasionally to help catch up with your sleep.
