At the time of the consumption, I was serving in the norwegian armed forces, where I had the time to do stuff like this. And actually, it was a perfect environment. Me and a friend had been at the drug store earlier that day to get marezine, I don't actually know where we got this idea, but we did.

Effects
Aggregated from 8 single-substance Erowid experience reports; 4 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.
Too few reports for bars: these effects come from 8 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Also reported in combinations. In the 4 Cyclizine reports where another drug was taken too, 1 mentions hospital, emergency services or an overdose, 0 a seizure and 1 psychosis (too few reports for percentages). In the 8 single-substance reports: 2, 0 and 0. These are not in the figures above: they cannot be put down to Cyclizine alone, and a mention is not always something that happened to the writer.

I found a bottle of cyclizine in my medical box that my ex had left behind when she left and I liked the sound of the name so I decided to look it up. Time: 10:22 pm I read on a website that the effects didnt kick in for a couple of hours so I decided to pass the time with some porn and masturbation as I have found ma...
Being just a youngun, I (stupidly?) took some older friends advice and ate 8-10 tablets of Marezine one fine summer afternoon. They told me all about these wonderful acid like side effects, except one small difference, being that 'whatever I imagine, will come to life in 3D.' I thought, 'Sure, right.' I started out sit...
I have never really been a big fan of marijuana or alcohol (definitely a user, just not a big fan). I'm more into the instant gratification type of drugs, ie. MDMA, LSD, pain killers. I don't have to worry about smoking or filling my stomach with liquids I'm gonna puke up anyway.
It was a Saturday night in the late 1980s and my friends were having a little party. All of them were on LSD but me and the good friend I came with. We showed up late and all the hits gone. We heard of Marezine from other friends who took about 5 pills and reported that it was a bit weird.
I've tried just about every common drug there is to try and have had a positive experience with the majority of them at least for my first time. One of the few exceptions to this that stands out in my mind is your basic motion-sickness 'trip'.
Ive done diphenhydramine, dimenhydrinate, meclizine, and cyclizine. I first decided to report on cyclizine. However, Ill refer to these other substances briefly. Firstly, I caution against taking any of these substances in high amounts. Too much can cause a scary, near death like experience.
I was recently rushed to hospital with suspected Meningitis. I had a viral infection with all the same symptoms so they kept me in for a few days under obs. Im 22, eat healthily, dont drink smoke or do drugs, and generally Im really fit and strong I go gym regularly, and to be this ill was very concerning for the do...
