I started taking painkillers and opiates about 9 months ago. I was in a car accident and got facial reconstruction and severe back problems. I was prescribed lots of opiates and really enjoyed them. Opiates are really nice but the dose to take gets increasingly high for a good feeling.

Anecdotal and clinical observations suggest tolerance to sedative/euphoric effects can build rapidly over days of repeated dosing and decreases over several days to weeks of abstinence; robust quantitative data are lacking. Avoid consecutive‑day recreational use to limit dose escalation and withdrawal risk.

Hello, this is my report of my first experience with the muscle relaxant/sedative carisoprodol, soma, and how it led to my month and a half long psychological dependency/addiction. It all stated one night in February 2006. My four friends and I return from a night at the park. 9:00 P.M.
This is a journey from the first time I deliberately took Soma to the most recent time. A few years ago, I was into all kinds of illegal drugs, but not yet into opiates.
I am a 22 year old male who has done nearly every drug under the sun (except crack and heroin). I couldn't even list all the drugs I've got under my belt because I wouldn't be able to remember them and it would make for an extremely long list (easilly 40+ substances).
Although I have used Soma several times this report will detail my highest dose experience (4 350 mg tablets). Background: Being faced with another boring school day and wanting to get f'cked up, I decided to pop my remaining stash of Soma.
I recently happened upon some Soma pills that my friend J was selling. He let me get 5 for free and I took them home. That nights experience is as follows: Previous Substances used- Hydrocodone, Oxycodone, Cannabis, Alcohol Current Prescription Meds- Skelaxin, another muscle ralxer but I didn't take it the night of thi...
Soma is a crazy, highly addictive drug for me. Its almost killed me three different times and I still want to take it. Here is a detailing of the first time I overdosed on soma this is the only time I overdosed that I have much of a memory of. First off, I need to say that Soma causes me to black out NOT pass out.
The following is a description of possibly the stupidest most careless thing I've ever done. 8:30 Ingest 2 Somas. I chewed them up, it's the worst tasting pill I've ever encountered. 9:30 Not feeling anything from the first 2 pills so I eat one more. 9:40 Getting frustrated so I eat 3 more.

6th July, 2012 (New Financial Year, Day 6) 18.9 grams (15 caps, 3.9 stems) plus 10.7 grams (stuff at bottom of evaporator, mostly stems) = not enough. I go to the park to get the last two fresh specimens of the season. Surprisingly I find five caps. Three of them are immature, but I pick them anyway.
Ahh, what a relaxing day was today... well, it wasn't the most relaxing day of my life at all, but after being in withdrawal from Benzodiazepines for some days, finally yesterday I could I get a nice amount of Lorazepam, together with a tiny bit (and I mean, something like 10mg, very tiny) of Risperidone, helped me to...
Just got my hands on some Pain-O-Soma. %) I love diazepam, temazepam and GHB. I've always been interested in old-school sedatives and I've been wanting to try carisoprodol for a while because it's a pro-drug to meprobamate. I took 700mg on an empty stomach earlier while I was waiting for my dinner.
So a couple of months ago I ordered some Soma online. It wasn't the first time I had done this, so it was no big deal. The first time I tried it I took 3 or 4 of the 350mg pills.
