I got up tonight. I will be taking another Melatonin tonight as it has no adverse effects on me. The sleeping me I cannot take is Temazepam. That's also sold as Restoril and was used by a lot of people who used it with booze to go to sleep and often they never woke up. Melatonin is supposedly made my our brains to put us to sleep when we are young and as as we age it stops so we can enjoy being an insomniac. Boo. Hiss. I want to keep making it. I think my brain stopped making its own Melatonin when I was about half a century ago. The new Melatonin formula named 3a.m. is what I'm about to take. It helps me go back to sleep without being hungover when I take it in the middle of the night.
