My experience was wake up at 8 am, brush teeth, breakfast, Ragnarok, lunch ragnarok, dinner, take a bath, ragnarok till 3 am then sleep, and the same routine for 4 days. XD
I don't have enough stamina to play all night. My max amount of hours playing a game in one sitting would be 3-4 hours, then my eyes would gety too tired and I would have to rest for a while/.
