Maybe you shouldn't "quit" but always moderate your carbs. That's what I do, and I'm stable at my weight. I'd like to lose more, so I may do another deep low-carb regimen for a few months.
What I did was extreme low carb for one month (under 20g/day), then very slowly increase to under 40 for a couple months, then maybe 50-60 for another couple. I lost 40 pounds the first month or so, then a little more. I'm now 50 down from where I started and level. Now I'm eating up to 100/day and feel like it is too much though, as my blood sugar fluctuates too much (borderline diabetic).
I think a lifetime diet of lower-than-recommended carbs is healthy. I've seen a lot of evidence that our "normal" carb intake is too high in general.
