molly again, would it be ok?

yesterday i had around 60mg of pure molly and it didnt really give me that much euphoria, or maybe i didnt notice it cuz i was high from smoking so much weed that night. would it be okay to take like another 100mgs today (and if not, what about next weekend)? im not asking if it could give me a bad time, but what i want to know is if it could do some irreversible damage to my brain or something?
