It is taxing on the senses but if you are over staging fish you have to keep pounding them until they activate. If you leave the marks too early you will miss the bite windows. Set up in the dark in the morning and fish til 9 am. Go in and get breakfast and a nap then head out after lunch and fish til dark. If a front is approaching, make sure you are over marks as this usually activates the fish to bite. Give them a menu of all bait types as preference will change day to day and even mornings to evenings.
