Not advising you should take that much of course. Or even suggesting you take it again. Just saying if you feel like it, you can up the dose a quite a bit, put a blindfold in a cozy bed in a safe and quiet room, and the result may differ.
Also everybody is different. Some people just don't react much to psylocibin and there is nothing one can do :)
