I don't track calorie intake. My exercise is also either all lifting on some days, or all cardio that can't really be measured as far as calories burned on other days.
10 pounds is a lot for 3-6 months. Though I do not track calories, I think it would be easy enough to estimate what 200 extra would be on top of what I usually eat and get those extra calories from milk.
Sounds good. No need to track if you are consistent with your intake.
