I did exactly the same Kingleds. I lost almost four stone then stopped trusting the plan and piled loads of it back on. I tried WW, 5:2, and allsorts but had very limited success. I'm back with SW now and I'm doing it strictly by the book - only weighing and counting what I'm supposed to. And the proof of the pudding is in the eating - I lost 6lbs in the last week alone and ate LOADS. It works - it just does, no need to sweat it.
