Last 10lbs

So I reached my initial goal of 150lbs about 6-8 weeks ago and have since tapered off with the heavy exercise and have continued to maintain very well (149-151lbs). I'm now considering going for a goal of 140lbs. I am 5'8 and haven't been 140 since elementary school. I hear from a lot of people that this last 10 can be hard to get off. I am looking for any tips/suggestions if you've been in a similar spot weight/height wise. Right now I am exercising a few times a week, staying active otherwise and eating well and having no issue at all maintaining. I don't want to end up fighting for this last 10 then having a daily struggle to keep it at 140 or thereabouts. I'm not a 1200/day calorie gal and I'm not going to starve myself to try to stay consistently in the 140 range. I would love to hear others experiences!
