I have found www.fitday.com to be invaluable when it comes to tracking calories/nutrients. Very easy, free online journal w/ built-in nutritional facts database.
I don't track everyday, but when I make a change in diet (i.e. bump up to 5000 cal/day, etc.) I'll use it for a period of time to make sure my eating is in order.
hell yeah, I do! I'm cutting though, so I have to. Actually overtime you pretty much start remembering what foods have what protein, carb, and fat content, so it only takes me 2-3 minutes to figure out how many of each of those (including calories) I have had in a day. It gets very very easy to do over time.
durig cycles i use to write everything down in a planner to make sure i was getting enough claories,,,,Got very tiresome and eventually i justy guestimated. I have done this for three cycles
