I used MDMA a year and a half ago on an almost daily basis where my dose started at 0.3g and ended at 1.5 . My max dose at one time was 2.5g. After that it did almost nothing, no rush and almost no euphoria....I was clean for a year and a half, after this time I decided to try MDMA again. So yesterday I got 0.5g and took one line and I felt no rush, almost no euphoria. Basically, I was in the same state as when I stopped using this substance a year and a half ago. I was expecting the tolerance to be much less and to feel the rush and some good euphoria. Another probably important info: I take Methylphenidate 54 mg every morning for my ADHD and Fevarin 100 mg in the evening for OCD. I will be glad for your advice or rather an explanation.. Thank you🤯
