No Energy

[Jimgolf]

Mountain Dew and Snickers is a glycemic nightmare. Try having fewer processed carbs in the afternoon. Sugar makes the insulin level go up; insulin makes you sleepy. Coffee and a low carb snack bar or a piece of fruit (fruit has a lower glycemic value than processed sugar) should do the trick for a quick pick me up, unless you are sensitive to caffeine.

Stick to whole grains, salads and protein for lunch. At any rate, cut down on the sugar, white rice and potatoes. Save those for when you're not trying to stay awake.

You also might want to get your blood sugar checked, if you haven't done that in a while.
