Do Not Try and Hole With Memantine 21 years of drug expierience. It all started with Dextromethorphan and then Methoxetamine, I fell in love with dissociatives. Since MXE is no longer around and I no longer get any good results from DXM, when I heard of high doses of memantine being similar to MXE or mushroomesque even...

Summary
Memantine is a dissociative substance of the adamantane class that produces long-lived dissociative effects when administered. It is a derivative of amantadine and is pharmacologically related to compounds like PCP, ketamine, and DXM, although its recreational use is comparatively rare. Memantine was first synthesized by Eli Lilly and Company in 1968 as a potential agent to treat diabetes.
Perspectives
“This drug is certainly fascinating. Not entirely enjoyable or fun, except for some tinges of euphoria at the beginning, rather it just felt fundamentally and deeply neutral. Itβs essence was elusive and mysterious, it felt as though it was a drug that existed at the fringes of consciousness that simply was not meant to be understood.”

Anecdotal reports suggest tolerance builds with frequent or daily use and decays over weeks of abstinence; cross-tolerance among NMDA antagonists is commonly reported by users but lacks controlled human data. Given memantineβs long half-life, apparent tolerance may reflect persistent baseline plasma levels rather than receptor-level adaptations. Data quality: anecdotal.
Cross-Tolerances
Effects
Aggregated from 10 single-substance Erowid and 10 Bluelight experience reports; 18 Erowid reports where another drug was taken too are left out
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.
Rows resting on fewer than 20 reports show a count (“3 of 7”) instead of a bar. Why 20?

Also reported in combinations. In the 18 Memantine reports where another drug was taken too, 2 mention hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 10 single-substance reports: 1, 0 and 0. These are not in the figures above: they cannot be put down to Memantine alone, and a mention is not always something that happened to the writer.

My Most Recent Experience I had only been home for a few hours after my week long New Year's trip, I had been staying with friends, drinking and celebrating the beginning of 2017, before I knew I wanted to make my first voyage into the Memanverse that night.
I had only been home for a few hours after my week long New Year's trip, I had been staying with friends, drinking and celebrating the beginning of 2017, before I knew I wanted to make my first voyage into the Memanverse that night.
I am a relatively experienced DXM tripper, and was really bored, and I remembered that there was alot of samples of Namenda in the cupboard so I looked it up online and it sounded like it would be fun.
Disassociation with namenda Today is 11-10-2014. I am a 150 Lb male in good health, not taking any medications or supplements. I recently came acrost some 5 mg Namenda (Mamantine) pills. After some research showing that they were indeed psychoactive I decided to eat them and see what happens.
I wanted to contribute my experience with memantine/Namenda not as a recreational drug but as a nootropic and antidepressant. Obviously, for recreational/psychedelic purposes, memantine is not going to be anyoneΒs first choice, and I donΒt think this is a productive use of the compound.
Addendum: 15-month follow-up This disaster of a trip is largely my own fault. I did not heed any advice I read online, went into it under the worst possible conditions, and took a higher starting dose than recommended.
Citation: Lazyvegan. 'A Few Words of Caution'. The Entheogen Review . Winter Solstice 2003;12(4):132-4. In the interest of harm reduction, I feel compelled to write this report. I have determined that memantine is indeed a psychoactive substance.

Age: 21 Weight: 120 lbs Dosage: 150 mg oral Setting: My apartment T0:00-Fifteen 10 mg memantine pills ingested. A quick shower was taken. T0:30-First notes arise, a very slight feeling of dissociation and dizziness melding with a sense of joviality and euphoria.
Age: 26, Weight: 140lbs Dose: 150mg oral + 75mg oral redose at around T-09:15 My intentions with this experience are: to explore this compound further (in ascending dosages), to help me gain some insight into some current predicaments in my life, and also to take a nice mental vacation.
Excerpts from my log (will explain and continue further) T+0 Began from a very moody morning. Did 2.5mg Lorazepam, had a good meal at McDonalds, and T+20' later did 10mg Memantine with water. T+40' Did 20mg more Memantine with Coke, began to feel ... more aggressive? T+60' Did 20mg more Memantine with Coke.
A much overdue update on my experiment! Background: I'm a veteran dissociative user, having used NMDA antagonists fairly consistently for about 9 years now. Started with DXM then ketamine, then 4-MeO-PCP then MXE and dabbled with 3-MeO-PCP and 3-HO-PCP.
Stomach: almost empty. Have some Alprazolam and Clonidine in case I feel bad or too excited. T - 1.00: I take 75mg Lyrica T - 0.30: I take 100mg Modafinil T - 0.00: I take 30mg Memantine with a Red Bull. Smoked 2 cigarettes.
Greetings to all. I take memantine daily - 20 to 60 mg at the moment. Lately I've been trying not to exceed 40mg (20mg in the morning and afternoon) orally for many reasons.
MEMANTINE - First Time- A few words of caution...! Well this is the final version of this report includuding additional commentaries from my original posting in the 'Psychedelics' forum a few months back, so I figured this finished version deserved a place in 'this' forum for those you who may one day be searching for...
