Absolutely - enjoy the feeling, but USE the feeling to help you prepare...we never assume that we're cured - that's breaking the first rule (being powerless), and it's a basic tenet of being frum, too - never being sure, never putting ourselves in the way of temptation, because no matter what level we're on, there's no certainty.
But yes - enjoy the feeling, enjoy being clean, enjoy being close to hashem!
