Personally, I'm a big fan of cheating.

I'm a huge fan of cheating too. I just don't want the person being cheated be myself.

We've already cheated nature. Many of us are hoping to cheat death. Why stop there, when you can cheat sadness too?

I'm happy to cheat all of those things. However to cheat those at the expense of losing things I value---like my long term memory---is to lose purpose. I'd prefer not to be sad, but if I must wirehead myself so that I don't feel sadness I'm sure as heck not going to do it by obliterating my ability to store my ongoing experience.
