Wow, weird, I went through 2/3 years of tripping 3-5 times a week too, but it was in 2006-2008. I experienced a MASSIVE tolerance that has never gone...
And this was you just purely abusing or using DOC? I CAN'T IMAGINE doing it more than once a week and i haven't gone that far. The duration is so long that i need a day after to just relax. .. i couldn't imagine flying through a 3mg trip and then doing it again after the recovery day. Lol
