Thanks for your thoughtful concern, Mary.  And surpisingly, no, I don’t suffer any late afternoon/early evening lulls of energy.  I have previously attempted dosing 3X daily, but the simple reality is that middle of the day time is always erratic for me.  The result was often taking my meds late, or not all.  I would forget my head on occasion were it not permanently connected to me.  So that’s how we devised the 40/20 plan for the morning and evening.  And as long as I keep testing well, I won’t change what continues to work for me.  Have a wonderful day.  Fondly, Eric
