Oh yeah, it's definitely hard.
The whole philosophy behind SW is basically, it's a low-fat eating style. A lot of the emphasis is placed on making sure your meat is as low in fat as possible, filling up on speed fruit and vegetables, making sure you're eating enough protein and drinking enough water, and synned foods in moderation. It's a lifestyle rather than a diet, and it's aimed at getting you into good habits where you will develop a better relationship with food.
Hidden syns can be tricky. For instance, I've been making myself a chili con carne for months that's packed full of speed vegetables and lean meat. All that good stuff. Then I found out that the Colman's packet mix I was using for the sauce contained 7.5 syns. I'd had no idea, and it can be things as simple as that that will make a huge difference for you.
I definitely recommend getting yourself to a group, getting the books, and even if you only stay for a few weeks until you completely understand it, it'll all become a lot easier to take on board.
