I noticed that if i ate a breakfast & lunch that was high in protien is one thing that gave me a boost, carbs seem to relax me to much, another is drinking plenty of water especially in the mornings seemed to clear the fogyness out of the brain, another thing to get me more alert was taking a couple of multi B vitamins at breakfast time and another one at lunch time, worked for me
Oh, one other thing was just a medium pace walk for about 10 minutes used to get my motor running a bit better.
good luck
Brian
