Just because you're roughing it doesn't mean you have to ditch all your usual routines. It's not like you've returned to the dark ages; you're just spending a bit of time in the great outdoors. If you're an Internet junkie and the icon for your WiFi connection is futilely spinning in a hopeless circuit, we might not be able to help you, but if not, there are lots of other ways you can assure yourself all is well before you climb into your sleeping bag.
Think of your routine at home. Maybe you like a glass of water before bed or to wash your face one last time before you tuck in? Go for it. Or do you like a final potty break before you hit the sack? That's fine, take care of business.
On the other hand, it can also be exhilarating to find yourself in a new environment, experiencing a novel way of living far removed from your comfy recliner and your frosty refrigerator. You can listen to the sounds of nature rather than the evening news. You can delight in the crisp, dewy air rather than the canned coolness pumped out of your air conditioner. You can fall asleep thinking about the hike you have planned tomorrow or the size of the immense smallmouth bass you plan on hooking. Let those daydreams lull you to straight into what, we hope, is a very restful sleep.
