Unfortunately most of my sits are all day sits. I drive a little over 100 miles to where I hunt and then a 30-40 minute hike to the stand. No place to go mid day but back to the truck so I just stay put. Sandwich, a couple of granola bars and two bottles of water usually does it for me.
Acorns, pine needle tea, and clover for me...I don't want to eat anything that will give me away! JK peanut butter sandwich, apples, various bars or candy, paydays are nice cause there's no chocolate to melt, coffee, water, pop in 20 oz bottles. I typically would never drink on stand but I did bring a can of guiness in one afternoon after a long day at work and it was delicious with a peanut butter sandwich for dinner.
water, good ol' can of bbq vienna's, apple, and granola just in case the sausages don't carry me through...
