Very restless during carb loaf

Just started carb load for my first marathon in three days so I'm targeting 480g/carbs/day which works out to about 2300 kcal. However I expect I've been in a bit of a surplus all week due to taper. I have SO MUCH energy it's hard to sit still and I don't know how I'm supposed to do this for three days-- anyone else?? Will this extra energy stick around for race day/benefit me? TIA!

Edit: Yes there was an unfortunate typo! I cannot fix it now sorry yall
