insomnia
"I have taken Ambien CR on a nightly basis for nearly two years now and have found that it is truly helpful. I have found that after a year or so on a 6.25 mg dosage I had to go up to 12.5 mg in order to achieve the same result. Other than developing a tolerance to it however, I have found that Ambien CR is extremely effective. I am able to fall asleep easily and my sleep is a very peaceful one that leaves me feeling well rested in the morning."
