EDIT: I have a sleep disorder and need a lot of sleep and I have to take medication at 2am in the middle of the night to ensure the rest of my sleep is REM sleep. I have tried a cheap wrist watch that vibrates for about 30 seconds but it doesn’t wake me up. My husband works long hours and setting an alarm that sounds to wake me would wake him at 2am so it needs to be something else. Any ideas, suggestions and brands of products would be appreciated. Thank you!
