Rolling 2 days in a row is a bad idea, serotonin after mdma is like a garbage truck picking up a trash can at the end of the week, dosing a 2nd time without waiting would be like the garbage truck coming around again yet again 8hours later taking the scraps and then burning the house down.
Get crossed eyed the 2nd day id say if your up for it
2ci and mdma then a small bump of mxe post-roll (to keep you going) any good?
