"i used to take lunesta and it worked fine but i went back to ambien. then i stopped both and my insomnia is back a year later. personal issues. i decided to try lunesta because ambien would make me so tired i couldn&#039;t wake up in the morning. with lunesta i can wake up before my alarm clock. that&#039;s exactly what i needed. i haven&#039;t tried taking it for more than 2 months. hopefully the effect doesn&#039;t wear off. if so i&#039;ll have to just go back to benadryl."
