MXE and lorazapam gives me pretty interesting OEV's(when I'd never get any from each substance alone, mind you). A lot of object recognition issues, and especially moving objects(seeing lamps fly around the room, patterns on tapestries buzzing around my head, things of that nature). Interesting combo although tends to lead me to a somewhat psychotic(or delirious?) state of mind. I actually stood yelling at my wall to stop letting it's patterns fly off at me.
4-AcO-DMT+MXE is hit and miss, but overall experiences seem to be positive.
MXE+weed makes both highs much more intense, but this is well documented.
MXE+25i-NBOMe adds to thought loops and visuals, and seems to bring out some vasoconstriction(I usually don't get any from 25i).
MXE+opiates, especially oxycodone, is amazing, makes both much more potent. I do a SMALL amount of mxe added in with my lines of oxycodone to roughly double the potency of the oxycodone and increase nodding effects. Keep doses low.
MXE+stimulants leads to racing heart, megalomania, and psychotic symptoms. Surprisingly, memories consider the experiences pleasant, especially MXE+amphetamine, if strenuous on the heart.
MXE+Alcohol leads to an intensification of confusion. A single glass of wine while on MXE makes me much more intoxicated and actually feel drunk.
Also, MXE used after MDMA, MDAI, and bk-MDMA sessions helps me sleep but noticeably increases heart rate. This combination feels the most dangerous of any.
