Weird boarder vision from GHB

[Synaps3]

So I noticed for about a day after I take GHB, I get this weird black and white pixelated pattern around the edges of my vision, but it only happens when I open and close my eyes. It only lasts like 5 seconds max and then dissapears completely. Does anyone else experience this or know why this happens? I am not really concerned because it doesn't seem to be getting any worse.

Don't rule out these two could be totally unrelated. Treat as two seperate things. The pixelated pattern never occured to me a day after I had taken a single dose of G. Repeated dosages, which quickly lead to addiction and withdrawal, do cause all kinds of worrying symptoms. So how is your usage, you have not mentioned any usage pattern? Do you have medical conditions/ take meds?
