No Sleep

Starting around June 9th I began to have trouble sleeping.  This carried on for two nights.  Thinking this was a result of too much caffeine and taking dayquil do to a nagging cough, I stopped drinking soda and stopped taking the cold medicine.  Unfortunately those two things did not help and by June 11th, things had rapidly gone from bad to worse.  I began to hear music and people talking when there wasn't anyone around.  I will be completely honest when I say I was extremely scared.  My paternal grandfather was diagnosed (at approximately 40 years old) with paranoid schizophrenia.  Also, my dad's only other child (my half-sister), was diagnosed with paranoid schizophrenia at approximately 20 years old.  I contacted my Aunt to find out what symtoms that they had exhibited.  My husband was very reassuring and promised me we would figure things out.  Keep in mind it has only been 3 days.
