Speaking of sleep aids, I recently tried that Sleepytime Extra by Celestial Seasonings.
I'm sure if used properly it would help with sleep with no side-effect.
BUT...
Being an addict, I, of course, loaded my cup up with five bags instead of the recommended one.
Had to get up in the middle of the night and found myself shuffling instead of walking, and the next morning I had the worst "hangover" without even drinking.
I guess the takeaway is that, to an addict, ANYTHING can and will be abused(!)
