"this has been very helpful for me.  my sleeping pattern has been messed up for years since having a daughter with a significant disability which included among many other things a sleeping disorder. ambien has enabled me to fall asleep consistently after a short period of time trying to fall asleep whereas i used to more often than not lay awake for hours before falling asleep.  it is interesting for me that there has been a couple of times where i was not able to go to bed for over an hour after taking it and it didn&#039;t seem to make me feel any more groggy or sleepy, but when i did finally go to bed, i fell right asleep."
