Bad mood after liver flush?

Did flush number 8 last week, changed the interval to 3 weeks instead of four to see how I'd go. Results were as previous flushes, mostly green and tan 'stones'. But here's the thing, I've noticed after the last few flushes (maybe all of them?) that about 4 days afterwards I get in a really ***tty mood for 2 days or so afterwards. This has been too consistent to be a coincidence. Can anyone explain that to me?

Thanks
