Are they zopiclone they do make you a bit dopey but you heal so much better asleep you can get a bit of metalic taste in your mouth personaly insomnias not give much support but they can realy help better to be dopey with them than dopey through lack of sleep dont worry about addiction they only give you a few and can get your sleep pattern back thats just my oppinion of caurse but ive sufferd cronic insomnia for years its a nightmare .p
