Hey, congrats to you! I'm pretty much in your exact boat.
I started the year at 267 and I'm down to 225 now. My goal is an even 200 (or I'll sometimes say 199 for the joy of seeing that 1 in the front).
I've done it just as you have -- by eating less. At the start of my diet I was counting calories on a daily basis -- but after a while I started learning to pay attention to the calories of everything I eat. Now I simply keep a running tally in my head and know where I'm at. I'm fine with estimating when I need to.
The biggest change for me is learning to be happy with smaller portions. I used to eat 3 enchiladas, then have another 2, then another 3,.. THEY ARE SO DELICIOUS! Now I know going in that I'm going to make my plate and that's it. There's times I wish I could have more, but enjoying the one plate is the biggest key to my success so far.
The other side of it is avoiding calorie landmines. It's so easy to accidentally eat an extra thousand or two calories while eating out by not paying attention. Knowledge is power :).
