I've just had my worst session. Ever.
Found some fish at 2/4 and 3/6 on Eurolinx. One in particular was 90/45 I kid you not, and he was calling down to the river most hands. I had perfect position on him on two different tables, and he sucked out on me hand after hand.
I played long after the whale had left with tables that were loose on the whole. I don't think I played that well, identifying a number of mistakes at the time. On the other hand I don't think I played so badly either. I seemed to be getting into a lot of tough positions - my raises got no respect and I frequently faced three bets to my raises or raises to my bets. I called down thin and ran into monsters, or folded and felt like I was being run down. It's a horrible feeling and I suppose is the beginnings of tilt.
It was a massacre: $300 dumped in quick time. I guess in the context of downswings, that one isn't so bad (50-60BB) - but wow it still hurts.
