Can you talk about what kind of tilt you experience?
"This hand is very marginal and I need to fold it. Do not play this hand when it is my turn to act." Then when it is my turn to act, I raise. WTF. I lost $100, so it makes sense to sit at a $100 buy in table and try double up
What triggers have you identified put you on tilt?
Losing a hand that I 'should' have won - even if it is only 65/35. AAQ7ds all in pre against KKJ3, board has J33.
Especially in a tournament where I go from chip leader to simply having no hands hold up, or missing every flop I raise, or playing position and getting 3 or 4 bet and having to fold, and the chip stack dwindling - occasionally feel very angry and upset despite still being well above average chip stack. When I try to make a play and get beaten - if the player simply outplayed me I feel like an idiot and an inferior poker player, if the player beat me by sucking out I feel angry at 'poker'. 
One of the worst combinations I have had is two massive 200BB bad beats in a row, folding a speculatve but marginal hand immediately after while trying to control the tilt, only to see two opponents go all in and watch the board give me what would have been a royal flush. Then I throw all my money away - so come to my table, folks 
What thoughts are you having when you go on tilt?
Persecution complex-style stuff. Like an exasperated 'why is this happening??' and 'Why can't I just NOT WIN THESE HANDS WHERE I AM SO FAR AHEAD??' and a combination of anger and despair.
I just get such a 'WHY CAN I NOT HIT A FLOP' with a dismissive sigh as I watch my chip stack dwindle and my name drop further and further down the leaderboard. Very disheartening to 'run bad' for even 5 or 6 flops in a row, and instead of just sticking to regular play and keeping with what has succeeded before I feel shit and unable to play A-game. Everything begins to feel terrible.
I also go from 'I can win this. I just need to keep doing what I do and get my money in good and hold up and I can win this. This guy does, x, so I can exploit that. This guy never defends OOP, so raise him. You can do it' - I go from that to quite the opposite...
How do you act when you're on tilt?
Total gamble and hope to get lucky. Typical way of trying to force pots to myself. All in with 9Txx on JQK board after being 4 bet by villain. Play 60-75% of hands. Get steamed, angry, hating everything. Get very angry, not even thinking about mathematics at all, not analytical in any way, pure betting and calling when I am pretty sure I am beat - basically play how i describe bad players. That is - hope to get lucky.
