not sure if normal during pregnancy, i have mentioned mine to a dr. since being pregnant, and they dont seem concerned.
ive suffered from insomia for about 8 months, the earliest i sleep is 2am, some nights i dont sleep at all, literally.
so i just want to say i know how awful it is for you.
advice i got given, was make sure your bedroom is a place for sleep only, no watching tv, on computer, paying bills etc
so your brain will associate your bedroom only with sleep.
also, get up as soon as you wake up, dont go back to sleep, although it may be very difficult!
do some sort of activity during the day, like a long walk, but not too soon before bed.
i havnt been able to try these methods, because of awkward circumstances, but maybe its worth a go!
also, try to avoid hot baths in pregnancy, warm baths are fine, but not hot.
hope you manage to get a good nights sleep soon!
