It's very difficult to say. The only thing I can tell you is that usually a 4 month break is enough to get rid of most of the negative effects of MDMA abuse. Most people will feel a lot better after they take a 4 month long break.
For a typical person, 4 months break after taking a piperzine pill is more than enough to get back to normal.
How often did you use MDMA before your current break?
The feeling you describe can happen on the peak of a MDMA roll, but you shouldn't be experiencing this 4 months after your last pipe.
Have you talked to a doctor about this feeling? What about your road rage stuff? I would highly recommend talking to a doctor and telling them everything you told us. It's just too difficult to isolate the root cause of your problem with so little information.
The following is a long read, but I beg you to please read it, and offer me anything. Im desperate. I feel like my brain is rotten, like im going crazy. Please, this means my life. Doctors just feed me pills. I pray to god for something else to save me.
I started using E, from November 5th, to Jan 22nd 2011, easily 10 pills each month. Every roll was better than the last, had mild comedown, always felt back to 100% normal around two days after using.
Until I unknowingly consumed a blue dragonfly pokeball containing MDxx and my first non-pokeball ever, a blue rolex, very speckled, and the dye would just bleed and melt onto my fingers whenever I held it. Contents of that pill are still unknown, but I'm leaning wayyy towards piperazine, as I have read reports, and talked to people about that pill around the same time.
My friend also rolled for his first time, 14 years old, took a blue rolex from the same batch, along with a red (something) double stack, and was totally fine the next day.
Me on the other hand, I didn't make it, the blue dragon fly went as any other roll, then made me very tired. I decided to bite the rolex in half, then take the second half 30 minutes later. 15 minutes after that i was floored, felt like I wasnt in my body, everything was light, my head had 5000 negative things running through it, I was pacing back in forth, sweating, freaking the fuck out. My whole body went numb.
I had intense, body tingling, eye wiggles, the whole 9 yards, for 18 hours. 18 fucking hours I rolled in my friends bed, but it never ever felt good. I was praying to god for it to end. I contemplating suicide during the whole thing, because of how awful I felt, and it just wouldnt go away.
I threw up 6 times, straight blue and green puke. I didn't sleep for almost 3 days, couldn't eat. I cried basically every hour for the next week or two, breaking down for no reason. Just balling and feeling numb.
I never ever recovered. And here I am, telling my story, pleading for help. I feel like I destroyed my brain.
