Hey Harley, I work from 1330 to around 0400 most nights and I have been using the same thing as what you would call Tylenol PM. Military name is NEX PM or something like that, neways, it works great and I dont feel groggy the next day. I am up around 0730-0800. OH, and I dont feel I need them to sleep on every other saturday which is my day off......your tax dollars at work! lol:yes:Come on it's not even late yet. These last few weeks I've been up 'till 2 or 3am. Now granted most mornings I've been able to sleep 'till 8 or 9, but it does start to wear on you over time. I've actually been thinking about trying one of those sleep aids, but don't want to start relying on them.
