Try not eating within the last few hours of going to bed, set a decent bed time not to early and not to late, remove all caffeinne and sugary drinks, if possible try not to nap during the day or late afternoon, remove books and tv's from the bedroom, use a bedtime routine like having a warm shower a warm drink and climbing into bed. One of the most important things is to remove as much light from the room as possible. Light inhibits the release of the sleep hormones (which pg hormones can conflict with to), so even the alarm clocks should be covered and try covering any window light with a heavy blanket.

My ob always try to reassure me that for the most part antenatal insomnia was more mental insomnia than a physical. While it felt like I had not slept a wink during the night, that my brain was continuing to run nonstop thinking and was sure that I was completely awake, that my body and mind was in fact sleeping in a very light sleep. DH also let me know that there was times were I would say I havent been asleep and he would laugh and tell me that I was snoring my head off.

Having it really does suck, and it can make you feel depressed and anxious but I came to the conclusion it was preparing me for lack of sleep when bubs came and kinda learnt to go with the flow of it. The more anxious you feel about sleeping the worse it can make it.
