This is such an embarrassing story to tell, however, if one person doesnt make the same mistake then its worth it to me. The worst part of this drug is that I have lapses in memory and once I am under the influence, I take more and everything spirals out of control.

Summary
Lorazepam is a classical benzodiazepine known for strong sedative and amnesic properties. It should only be used for short-term relief due to rapid tolerance and severe withdrawal risks. Never discontinue abruptly after regular use; tapering over weeks is essential.

Based on reports from:
Tolerance
Build-up
develops over 1–4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
Reset
weeks to months depending on half-life and duration of use; taper recommended
Tolerance Decay
Full tolerance
14d
Half tolerance
7d
Baseline
~28d
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Sedative/anxiolytic tolerance can develop within days to weeks of continuous use; recovery is gradual over several weeks with abstinence. Values are approximate and conservative; individual variability is high.

I was prescribed Lorazepam (Ativan) to allay my social anxiety symptoms. I was instructed to take 1 to 2 .5mg tablets 3 times daily. I had already tripped on the stuff prior to obtaining my own prescription and I loved the way it made me feel, so I never followed the dosage recommendations and took the pills recreation...
I'v been taking Ativan for about a week now. 1-2mgs 1-3 times a day. This drug makes me feel rather slow and muddled. It is of course a downer but along with the usual effects of a Benzo (i.e. xanax, vallium, ect.) comes a sort of uneasy, queezy feling, espesially when exeeding recommended dosage.
Im in my mid 20s, over 6 foot tall. 2007 I underwent custom Lasik surgery on both my eyes. Prior to the surgery, all I had done drug wise was had a few beers the night before, and during the week I had been taking my usual multivitamin and 2mg of Acetyl L Carnitine I take daily.
A few years ago I had a few very bad experiences with Klonopin, that resulted in my hospitalization due to the paradoxical effect it had on me. I ended up hurting myself as well as a few policemen who happened to be in the wrong place at the wrong time. I was deemed clinically insane and no charges were ever filed.
I have used almost every drug the government tells us not to, and all I can say is that my life, all thirty years of it, have been one hell of a discovery. My relationship with mind altering substances began at 15, and I have no intention on stopping now.
It's amazing how much a small decision could impact someone's life forever. It may not seem like such a big deal to the 'hard-core' drug users, but it changed my life forever. I have a couple experiences with over-the-counter highs (benadryl) like a lot teenagers.
History of user: 29 y/o female. Experimented with a variety of psychoactive agents in college (LSD, mushrooms, ecstasy, ketamine, cocaine, marijuana, etc.) both recreationally and as psychoactive growth opportunities.

So i got my ativan script filled early today, a week early in fact (poor little heart patient ), anyhow i was feeling edgy and tired at the same time, so i decided to take 2mg Lorazepam at 9pm. Fun stuff ususally, really helps the insomnia cracked out feeling.
This is the second time I've ever taken a benzodiazepine in my life. I have taken one clonazepam pill a couple months back, but it didn't do much since the dose was small. Either way, my point is that I have pretty much no tolerance to this stuff.
another incident from me i took ten pills(10mg) effects was like this: i saw different colored-sized "light clouds" moving freely in the air. i could touch them and when i do it my hands color turns to the color of cloud which i play.
I got some lorazepam, so for my first time I decided to take just .5mg. Basically, it was very weak. t+30min - can feel its effects coming in.. minor sedation t+60min - small euphoria being experienced, possibly placebo. Feeling more sedated but not much. When walking, I feel a little weak in the legs.
im going to post some of the craziest shit. about ativan, sleep deprivation. like 2 and half days maybe three days. because i was detoxing from 15 maybe more. days of hard core drinking. when i quit drinking, i puked 7 times in 24 hours! totally sucked.
I know this report sounds unbelievable and ridiculous. But This combo almost drove me to suicide .I use cannabis daily .I also use amphetamines probably 4 or 5 times a week.
This happened almost exactly a year ago. I was a benzo addict and I found out about a week earlier before this "trip" that I was going to rehab for Xanax/Klonopin abuse. I am an epileptic so naturally I get scripts of Ativan for potential seizures.
Preface: I am diagnosed with Generalized Anxiety Disorder and Panic Attack Disorder. Medications I've tried to help treat this (acquired either by doctor's prescription or attained by my own accord) include many "weaker" anxiety drugs as well as benzos: klonopin, valium, xanax, and ativan.
