Thanks to the OP for posting this thread. Credence to what he is saying:
The major fuction of this forum is to discuss and inform people of the possible consequences and help them be as safe as possible in their psychedelic consumption. Of course, people respond differently to the same chemical - But just because you haven't had similar adverse effects as described here - doesn't mean you should write off the many others who have experienced it and are concerned. The only reason they are taking the time to write up about their experiences is to help inform others so they can be informed of the possible adverse effects before choosing what they ingest in their body. I think this is the principle of why this forum was started in the first place. I also understand some of the complaints of users about "over-generalizing", which are valid - but as far as 2C-I - I can confirm a lot of what the ops and others have experienced. It may not happen to everyone, but my glaring obvious, almost daily obstructing effects have lasted over 2 1/2 years! and are just now starting to get better.
First off, the only psychedelics I have ever done are Shrooms (30+ times over 5 years) and 8 Doses of 2C-I in a little under half a year - most doses were between 18-22mg - always at-least 2 weeks apart. The problems started right after my 4th or 5th time using 2C-I and got worse the other couple times I tried it. Although I have to say, 2C-I was always a beautiful trip for me.
My effects were not as much visual changes but rather a persistent perception/body chemistry change like the OP is discussing. The left over effects had both negative and positive applications, which are all similar to the plus and minuses while on 2c-I itself.
1) For 1 and 1/2 years straight, I felt like I was on a medium dose of stimulants, non stop. Even in my sleep, I would jolt from laying on one side over to the other - with the speed and intensity of being on 30mg of Ritalin. I ended up having to take neurontin to help slow my body down and get past the awkwardness of feeling like I was on stims for weeks on end - with a feeling very similar to the 2c-i bodyload, but in ways worse and more "off". My mental bandwidth was also that of being on 30mg Ritalin - it was flying much faster - connecting thought after thought sometimes too fast for the conversation I was in, which would create a jittery anxiety in social situations. This stimulant effect is just now starting to slowly reduce itself 2 1/2 years later! I also felt very mentally / personality wise "off", for a period of time a lot of my personality disappeared - the only thing that would bring it back fully at the time as Neurontin (Gabapentin). However, this is finally back to normal - but for awhile I would feel "locked up" - my personality felt frozen my body and muscles at times would freeze up - like my face in social situations.
2) Spasms and Energy jolted through my body randomly. I've never had this before in my life, at first it was just these jolts of energy I would get through my body - like an overload release of stimulant energy that would make part of my upper body twitch strongly like a spasm. After a year of having the symptoms - the spasms got much much worse. Similar to a couple or users on this forum had. I began having hand and body temors, I would wake up in the morning and within 15 minutes I would have hand spasms/termors consistently - it even had this "are my hands coming or going" feeling like people discuss with Parkinson. My legs and hands then went through an 8 months period where they would get stiff, and lock up at period of time. Even while I was speaking my muscles would just lock up, and I would have to wait for them to unlock before I could finish talking at times. This lasted for 8 months and finally FINALLY is gone. I would wake up every morning, hoping not to have to deal with the tremors and muscle lock ups - but it would be clear as day
I went to two doctors, my mom is a doctor at a big hospital so I got access to some of the best diagnostics Doctors in the US. I didn't mention 2c-i use at all until after the diagnostics - because I was worried it might be something else or the 2c-i had triggered some other problem. After analyzing me, they said everything showed up fine on my tests, and the doctor said it looks like it was caused by Stimulant use, like the Ritalin I was on 9 years ago. Although, I clearly didn't have any symptoms like this in those 7 years of not taking ritalin before taking 2c-i, and all these symptoms started the Day after my 5th 2c-i experience. All of the 2c-i came from the same vendor so there was no different in synthesis. I then told the doctor about the 2c-i use and that it started right after then, and he told me it sounded right down the alley of what could cause these types of symptoms.
3) Also Right after that 4th or 5th dose, my metabolism seemed to go haywire. I would get incredible hungry out of nowhere, no build up or warning leading towards being kind of hungry - just a jump to feeling like I hadn't eaten in a day. Sugar really helped correct this as well. I also lost control of the sense of my bladder, all of a sudden I would have to pee like I held it in all day - with no warning or build up. It was never a real big issue =P but my monitoring of build up for it was completely gone for 2 weeks after.
