It's 5 o'clock somewhere

I do really well until 5 and then everything unravels.  Not sure if it's because I'm tired, bored, or a combination of the two.  I'm trying to stay positive and stick to my rules. 

 I've been tracking my food and to be honest, I'm not sure how many calories I should be eating.  I should call up my wls clinic and ask I guess.  Duh!  The good news is that tomorrow is a new day, right?
