"i took restoril for about 5 years. it really helped me fall asleep and stay asleep. when i woke in the morning i wouldn&#039;t have any hangover effects, i would feel refreshed. it also didn&#039;t cause me to sleep so heavily that i couldn&#039;t wake if necessary. unfortunately after about 5 years it stopped working. i was taking 30mg a night (sometimes a little more if i needed to go to bed earlier than usual). i wish it still worked, it was a great medicine while it lasted."
