I would recommend giving it a little more time. It is very regimented at first. You have to be vigilant of every little thing, counting and measuring and weighing. It's because you're undoing old bad habits and ingraining new good ones. As time wears on, things will become much more second nature because you'll have a better idea of macros and carb content and be able to quickly count in your head, or just know what works for you and what doesn't. It's a process.

I hesitate to use the word "relaxed" to describe how it gets better and easier because some (like me, for example) sometimes interpret that as being lax, i.e., "cheating" or being in denial about being able to reincorporate old bad habits that tripped you up in the first place. But I do mean relaxed in the sense where you just get used to choosing the right foods and behaviors that really do work for you.
