Good start! I agree that you need to weigh/measure your portions, at least for a while. This will help "keep you honest" and learn what a "normal" portion is. This is useful especially if you are eating away from home and need to estimate portions.
Low cal is OK for a while, but you really want to find a level that keeps you full so you're not tempted to overeat to compensate. 1200 sounds like a reasonable level if it keeps you satisfied. Adjust as neccessary.
