I assume you figured out DMT doesn't mix well with benzo's? I've heard of some unpleasant experiences being had after drinking so maybe it was better that you had taken the kolonopin, may very well have spared yourself a bad time!
50mg is sort of overkill for your second time. If you are vaporizing properly it should only take 20-30mg for a breakthrough. May I ask what type of smoking device you are using?
Welcome to the Nexus btw! You should check out the wiki if you haven't already, there is lot's of good stuff in there as well as some excellent pointers for getting the most out of the least amount of spice, you never can be too thrifty with that stuff, ya know?!
And what a molecule it is! What do you think of the experience compared to other entheogens? Mind blowing to say the least eh?
