Hi Gizmo, I had that happen. The doctor suggested I test during the night. Turned out I was having some serious lows during the night. I fixed it by having a bedtime snack, sort of.

Canta libre, Canta vida, de mi madre, y mi padre,
Canta mi corazon, Para los ninos, y sus ninos, canta libre.
I got music runnin' in my head,
Makes me feel like a young bird flyin',
'Cross my mind and layin' in my bed,
Keeps me away from the thought of dyin'......
I got music runnin' in my brain,
Ev'ry song with it's own kind of meaning,
Cleanse the soul and wash away the pain,
Baptized by the song that you're singing.
Canta libre, Canta la vida,
siempre conmigo, canta libre...
