"i took these every night for a week after struggling with insomnia, hate the groggy feeling sleeping tablets give you the next day so thought i&#039;d give these ago. worked perfectly with no side effects. went away for the weekend and forgot to take them with me. first night, didn&#039;t sleep at all, second night finally drifted off sometime after 7.30am and was woke at 9.45, last night got about an hour to 2 hours. was absolutely done in, got home and that night took a nytol and slept like a baby. my fear is can i survive without these tablets now. hopefully they keep working so i don&#039;t need too."
