"i&#039;ve taken both ambien and ambien cr. it caused interesting side effects from day one. i found that whatever was on my mind before taking the meds (i.e. i had to do laundry/clean the house the next day or go to a sale) i&#039;d end up getting up and doing them that night before falling asleep and not even remember it the next day!! i would vacuum at 2am, cook whole meals, get in my car to go to a tech store sale and come home with 100 movies (some 2 or 3 copies!)! my husband didn&#039;t mind the extra wild sex! it would have been nice if i would have remembered it too! the last straw for me was when a close family member passed away, i couldn&#039;t get rest so i took one to help. a month later, i found i had an accident i didn&#039;t remember! be careful!"
