Oh it's those school lunches-I just know they put "something" in them to control the students. I used to drink a Pepsi with lunch-I think it destroyed the additive! I think you were just a tad nervous about the first day and your body just reacted-it was shutting down to get rid of the nerves!! Next time go to the school nurse-sleep on the cot-I spent some lovely times in the nurse's office-sure beats the principal's office!! Well tomorrow is Wednesday and then come to the lounge on Thursday!
