I can say with almost one hundred percent confidence that it is highly unlikely that you have acquired encephalopathy (OBS) from your rather minimal use of GBL.
OBS is usually defined by someone who has been exposed to an organic solvent chronically (for years, five days a week, 8-10 hours/day...)
Not only that, but acutely diagnosing a disease to be an absolute effect of one specific drug is pretty difficult; there are so many other daily factors that can contribute to disease or illness - the drug could possibly be just a facet of the symptoms present, or maybe it has very little or nothing to do with present symptoms whatsoever.
GBL is removed from one's system after usually 6-12 hours. The first time you urinate after dosing, it's likely you've expelled most or all of the dose. A drug test for GBL has been developed by forensics, but with the short time it stays in the body as mentioned above, one would need to be tested for GBL in their system very very quickly.
You said you've changed a lot since you started using GBL - well, one could take a wild guess and say that you've changed because:
1. (obviously) you're ingesting a chemical on a semi-regular basis that your body was not used to ingesting prior to this.
2. my guess would be that you were introduced to it by someone; as opposed to you just searching around on the webs and ordering a gallon for yourself on some odd whim - which could lead one to the conclusion that you are hanging out with a 'new' or 'different' crowd of folks; in turn making small but noticeable changes in your personality (this could be either positive or negative, but it seems as if you have indicated a pretty strong desire to quit and have put a plan in action thus far to do so, and you are noticing positive results, which would tell me that GBL was causing preceived negative qualities for you...)
So, if you want to quit, you simply remove #1 & #2 from that list above.
It appears you've already removed the chemical....
So you asked "...if GBL could induce [encephalopathy/OBS]..." well, maybe - I'm sure it's possible... however, pretty unlikely. One would have to be taking multi-milliliter doses PER HOUR, every day - and before OBS or enceph. occoured, it's likely one would die from cardiac arrest or coma LONG before OBS was diagnosed.
Mind you - I think GBL is a very dangerous drug, and I have an immense amount of respect for it. I personally enjoy it on occasion, and yes - I really enjoy it, most of the time. Dosing GBL is so incredibly touchy, and there are about a bazillion factors that go into that day's dose that will dramatically effect the results of said dose. I never take more than 1mL to start off with, I'll wait a half hour or more and if I am feeling little to no effects, I will increase by 1/4 - 1/2 mL. Even with how careful I am, I've woken up naked in my bedroom with the porn blaring at high decibels so they can hear it over in Guam, and sticky as a bear eating a honeycomb (with lube, of course...I digress...)
My point being - GBL is touchy, potentially very dangerous, and should be respected and dosed VERY CAREFULLY or else you may end up doing the crappie flop in somebody's living room, with everybody watching you, debating weather or not they should take your goofy ass to the ER or not.
Be well! Dose carefully, and fap on.
