I drink 2-4 cups of caffeinated coffee each day and I really don't have any problems. I drink Red Bull every now and then, too. On days that I don't have caffeine I do feel "sluggish" but it's not awful. I enjoy the ritual of drinking coffee plus the taste. I don't have any problems sleeping unless I have caffeine very late in the day. I get a solid 7-8 hours of sleep each day without any problems. So, I don't really see the reason to quit caffeine.
