Hello and welcome to Healthcare Magic. Thanks for your query. I understand that you have been having sleep problems for which you are taking Nitrazepam. Like you have rightly mentioned, taking benzodiazeoine sedatives like Nitrazepam over a prolonged period of time can have a risk of dependency or addiction. There are several so-called natural supplements available over the counter, but their composiyion and effects are not scientifically researched. So, it may not be a good idea to take them regularly. If you would like to come off medication, I would suggest that you reduce the dose very graduall while practicing good sleep hygiene techniques. This will help you come off the medication smoothly. Wish you all the best. Regards, Dr. Jonas Sundarakumar
