I use the default timescale, and usually spend my days doing misc. quests and looting forts in search of Shadowbanish wine. I only sleep when I'm ready to level up, and then only for the shortest amount of time (an hour) -- though I'm toying with the idea of downloading Vim and Vigor (so you have to sleep and eat regularly). I don't care what time it is when I sleep, since I only really take naps... I visit the IC most, because that's where all of the merchants I use most are located. I think I use the IC because I have a lot of mods based there, like merchants. You know, Edgar's and the Mystic Emporium; the improved theivery (mod) quests and so forth. I travel to other cities if I need to sell stuff fast, and if they are closer than the IC. I try to limit fast travel to emergencies (like a short-lived feather spell) and never use my horse anymore. I really only go to other cities for quests, and don't spend too much time in them, except for Skingrad and Leyawiin which I like to visit. I have Kumiko Manor for my house, which is decidely off the beaten path, so I don't spend a lot of time there, just when I'm in the neighborhood. I have Frostcrag spire, too, but only go there for the alchemy lab since it's such a hike up that mountain.. Hope this helps you out!
