The Honey Stinger waffles are a good solution to your problem because they address the two things that you need to do, which are to 1) get slow digesting carbs (like the waffle part) into your body that will last throughout the day and 2) get some quick digesting/metabolizing carbs (like the honey) to give you the quick energy you need to cover being tired when you set down to glass. But they are not the only way to address the problem.
Let's look at the scenario you just gave us. Even at rest your body is still consuming calories and needs to be fed every few hours, even if you are just sitting behind the steering wheel of your hunting rig. It sounds like you probably drove straight through for 6-8 hours (two meals worth of time) and probably didn't eat much of anything or anything that your body really needed. Then you walked to your glassing location and probably just ate trail bars of some sort and water.
To give your body what it needs start out your day with a mix of slow burning carbs (oatmeal, granola, cold cereal, pancakes, Eggo waffles, etc.) and faster burning carbs that release their energy faster (unrefined sugars in the form of fresh fruit, dried fruit, honey, etc.). The slow burning carbs will give you energy throughout the day and the faster burning ones will fill your immediate needs. You can continue this pattern throughout the day to keep your fuel tank topped off. Also, mix in protein and fats throughout the day as you need those as well.
A pattern that works for me is:
~ Breakfast of oatmeal, milk or yogurt, and blueberries to start the day off.
~ Morning snack of fruit or grains or a mix (trail mix of raisins, peanuts, and unsweetened cereal is a favorite, maybe with some chocolate)
~ Lunch of some kind of carbs, protein, and non-starchy veggies (V-8 juice, pickles, green beans, broccolli, cauliflower, dehydrated or freeze dried veggies from MH, etc.), and some fat; this could be a tuna salad sandwich with a couple of pickle spears.
~ Afternoon snack similar to what I did in the morning.
~ Evening meal of the same mix as for lunch of carbs, protein, veggies, and fats.
~ Evening snack like the other snacks, but I like to include some kind of dairy then like cheese or more milk or yogurt.
This keeps me fueled and my metabolism up throughout the day and if I get hungry some more trail mix solves that problem since it is a mix of all the things my body needs (carbs, protein, fruit, fat, etc.).
Hope this helps. Just keep topping off your "fuel tank" and you should be fine throughout the day. I think you are winding up tired when you stop because you are "bombing" up to where you want to get and forget to keep eating.
