If that is your normal everyday experience you should consider changing your diet and or your toilet. Neither my wife nor I clog a toilet more than about once a year. The double flush might happen once every other month.

I don't think GP is saying he clogs the toilet, but rather that a single flush does not clear it. We have very low-flow toilets, and sometimes my little kids have to double-flush. It's not about diet or anything — the toilets are just very low-flow (assuming you only have to flush once).

I’d argue that clogging a toilet with any kind of regularity is still a failure of either engineering or diet.
