Out of bed 4-30 am not yet light

I had been laying thinking about this and that,
then this and that are going round again, time to
get up. This is a little out of character I am normally 
so tired  I lay there hoping it will stop and I will re-awake
revived, it never happens that way, 
So what was going round like a washing machine ?
That drink I enjoyed last week, Just not so happy about it now.
It did not get out of hand, so what is the problem ??? Me.
