"Charbucks" is Evil

When I hit the hay last night I wasn't even very tired, but I figured I better get to bed.  Wingnut had to sleep elsewhere because of work.  I never sleep well when he is gone as it is, but last night was particularly bad.  I must have tossed and turned for two hours before getting a few winks, only to be disturbed every time Baby Wingnut squirmed next to me.  I kept asking myself,  "Why am I still awake?  I only had the one cup of coffee in the morning.  What is up?"  Then I remembered the late afternoon "Charbucks" run with Baby Wingnut(he loves his coffee).  What do they put in that stuff?
