Ask HN: How to overcome the compulsion to comment?

I know it is useless (xkcd 386 says it all), but I can't seem to stop. Some topics just push my buttons and I have to dive into a useless discussion. Reading news is often a waste of time, but commenting makes it a huge waste of time.

I have cut out some push channels (like Facebook and Twitter), but I find difficult to block HN because it is my only news source.

I have already tried blocking my HN account and it worked for a while, but eventually I relapsed and started discussing again with a new account.
