Whether you are sleeping on a military cot or travel cot, or just your bed at home, you should be interested in these tips from the National Sleep Foundation.  They say that certain foods can affect your sleep, as well as how you feel during the day.

They don't break it down by sleepers of portable cots or even camping cots, but no matter what you sleep on, keep in mind of these foods:

• Carbohydrate-rich foods, such as pastas and breads, can make you more sleepy.
• Carbohydrates work well with proteins to induce sleepiness, which makes combinations such as peanut butter on toast, cereal with milk, or cheese and crackers good bedtime snacks.
• A large meal can make you more tired, especially one with a lot of carbohydrates.
• Caffeine in foods and beverages is a stimulant that blocks hormones in the brain that make you feel sleepy.
• While alcohol may help you relax and fall asleep in the short term, over the course of the night it inhibits the sleep process and can prevent you from getting deep, restful sleep.

Obviously, buying a quality sleeping cot can make a big difference, and my favorite folding cot always helps me sleep, but you need to do what's good for you.  Perhaps a good travel cot or portable cot will get the job done, and there are always camping cots, which make for great cot sleeping.  Those in the military are always sleeping on some great military cots, and they always seem chipper.
