"i have been taking the generic for ambien for a about 6 mths, i have a number of dieases and am now on a mild chemo ,i have alot of pain all of the time, so sleeping is hard, ambiem works, though i would never take it with out first making sure you follow all of the instructions! if you don&#039;t you can expect trouble with the side affects, i know i have, you can not take it and not get in your bed for the night with no distractions what so ever. i take it off and on &amp; it&#039;s working great for me!"
