oh Sleep, Where Art Thou Once Again

It's four am I cannot sleep I cannot think, I cannot weep There is no heaviness in my lids No sleepy sand, which to get rid

I sit here wanting, needing sleep But where oh where are those damned sheep I do belieive the wolves have come and gobble up,yet every One

So now I lay me down to sleep I am so tired, there are no sheep Now I must, I trust, I can Find a substitute -- Maybe the fan?
