Poak - yes, this makes sense.
I have had an evolution of symptoms over the course of 7 months since my last dose. MANY of them closely resemble some of the subjective effects of MDMA.
It sounds like your case is relatively minor, but I had dizziness/spatial distortions for weeks after use. I have also had sensations, sometimes subtle, on the nerves of my face and scalp.
Head-pressure can sometimes feel like rolling, when it isn't painful or bothersome.
This still happens, after 7 months.
However, none of these symptoms are associated with euphoria.
At best, they could be described as mildly pleasant - on rare occasions.
I have seen many anecdotal reports from other users saying similar things.
Some even have mild visual hallucinations along with their dizziness.
In medical case-reports, severe visual hallucinations have been documented, along with other symptoms, like jaw clenching and bruxism (teeth grinding). Keep in mind some of the ex-users had been abstinent for years.
MDMA 're-wires' the brain. This is considered a proven fact by most scientists.
Decreases of regional blood flow in the brain are common following use.
Increases sometimes follow, but this is less common. It is considered a marker of 're-wiring' and is often seen to last for months.
It is the consequences of this 're-wiring' that remain a mystery.
What you describe is entirely plausible.
Consider it a sign that at least one region of brain tissue is being 're-wired'.
The 5-HT system has been shown to recover over a very long, protracted period of time. You should give yourself a lot more time before rolling again. 1 year minimum, in my opinion.
The only way to speed it up is exercise.
Umm... What are you even answering here? The OP is asking if anyone else gets flashbacks from MDMA, not wondering about other effects, but whatever. You go on in your next post to talk about LSD which is completely irrelevant.
To answer the OP's question, yes I also get flashbacks sometimes. If I hear a good song, a song I heard while on MDMA, or am reminded of something I've done on MDMA then I will for a brief second feel like I'm on it again. Going to good concerts sober I sometimes feel like I am rolling as well. Crazy stuff eh?
