Isn't it a matter of saying to yourself, from now on:
Don't ride toeside at all, apart from when carving into a wave, or a fun frontside/backside carve in flat or chop
Just like everybody else does, here at least, meaning don't ride straight when toeside, but switch feet as soon as you know you are n gonna ride on a new tack .
You will be a clutz for some time if you haven't jibed (or tacked, depends on what you want) for a longer time, crashing a lot now - especially because you are so confident riding one feet forward always, it feels like a huge step back, so no wonder you don't wanna do it intuitively.
As you day yourself: Getting lazy
The next session, give yourself the challenge NEVER to ride toeside, and see if you can manage that
This way you still get half the time on your good side, and soon both will be almost equally good, and your feet switch transitions a lot better
