some nights i didn't even sleep at all. i would go for months without 4 or less hours a night. it had to be absolutely quiet, dark, my own bed, my own pillow or i had no hope of getting sleep. even with a newborn i'd be lying awake desperate to get to sleep.
then someone on this board recommended this website which is essentially trying to sell you a cd, but they send you emails with a programme of things to try. i followed their programme and it worked for me. it takes me 5 mins to get to sleep now. i was in hospital with dd2 last week and they insisted i keep the light on in the room. i was sleeping on a fold down cot. i managed to sleep most of the night even though nurses kept coming in and out.
i have no vested interest in this website - i didn't buy anything off them and i have nothing to gain by promoting them. i just hope it may help someone else.
