I took it when H went to bed. To make sure if I only slept 3 hrs or something I'm not up alone. My son gets up at 9 am. I'm usually up with him. tomorrow (skip tonight/ melitonin tonight) I'm taking it around 2 am. or earlier, if H goes to bed earlier. I do not like being alone when time is slow. I'm more likely to do something stupid or dangerous.
