I believe that it is better to try them on yourself for a week to see if they work for you. The most important thing is to do all of the following:
Make sure you have a clear and easy way to measure your weight. You are more likely to have problems with sleep if you are overweight or obese. Set a regular sleep time. Try to set your alarm clock so that you are up at least two hours before your bed time. Find an effective alarm clock. Some alarm clocks, such as those with an alarm sound, are not as effective as an alarm you set yourself. Get rid of the alarm clock. It is better to use an alarm that you set yourself. Sleep in the daytime. You will not be able to get a good night's sleep if you are in the room all night. Get some quality sleep before your alarm goes off. This will prevent the alarm clock from waking you up in the night. Try not to go to bed too early. You may get tired. Try to avoid being up too early. If you have a child sleep over at the parent's house, the older child has the advantage of an evening nap.
