Could you really give up completely even if you wanted to? Think about it.

The answer is no. Just simply having this background knowledge of lucid dreaming as well as an implicit awareness that you could be dreaming is basically a guarantee that eventually you will have another lucid dream. You could stop pestering yourself about RCs, you could throw away your dream journal, you could swear off all the *ILDs forever, but one day something fantastical is going to happen while you are going about your business and you're going to realize that the only explanation is that you are dreaming.

So what's my point? My point is this: the seed is planted. You will have another lucid dream sooner or later. I understand being impatient and wanting it to be sooner rather than later, but "giving up" is not really much of an option. You may as well just persist so that when it does happen again you'll be prepared to make the most of it. Plus, the more you invest yourself in lucid dreaming, the more frequently it will happen - it may not seem like it right now, but take it from someone who been into and out of practicing lucid dreaming a few times.
