We certainly do need our proper sleep Mel, its essential for our bodies to recover/revive, i reckon a few sleepless nights can really take a toll on us, especially if your working and need that 100% concentration on whatever you are doing.
Was Alan taken any of the suggestions here like Valerian with the magnesium or only just the magnesium itself ? those 2 combined sure put my lights out.

wide awake, at 1:19, scanning the board to see if I can be helpful to anyone, and I read your post and smiled. I guess this is on thread I'm not going to be of much help with. All I can do is commiserate. At 1:30 am and tomorrow a full work day. Oy.

Never mind Liza, you have certainly done your fair share of helping many people through out the time i have been associated with the old board and now this new one, good one
I use to be on the net for hours & hours through out the night trying to wear myself down so i could go to sleep, but i think i was really activating my mind more so than wearing it down, i try not to use the net at least one hour before go to bed at night, taking the valerian and magnesium a couple of hours before hand has been terrific, i haven't felt so good in a long time.
take care
Brian
