"i was taking ambien 12mg, which in my opinion is the best sleeping pill on the market right now. i heard about lunesta and i decided to give a try. my doctor prescribe the 2mg. hours passed by and i&#039;m still waiting for it to kick in. nothing. i made a huge mistake by changing from ambient for  lunesta. now i have to wait for a month to go back to ambient. if you&#039;re thinking of switching or trying lunesta. don&#039;t even bother. i guarantee you ambient is the best option"
