i do the exact same thing, i go on untill i mentally break, to the point where , when i walk past a pice of bread in a mall, that theres no holding anymore, then i do an absolutely epic 15k calories binge, and it dont even affect me badly, as everything is diarrhead out very soon after 
my record is 30 days btw 
but that was with higher fat intake.
those protein only days, my best was maybe 2 weeks
My point is that the diet will work better if a low-fat high carb refeed is used once a week. Of course, you would go 2 weeks no carb before you start doing this, but once you try it that way it really does work better. Most peoples weight loss starts to stall around the 3 week mark on a no carb diet and that is because of zero leptin being produced. As I said before, if using t3, it doesnt really matter, but I have found that the one day of carb loading on a diet like this makes you look way better during the week.
