Is it normal to see something like a gnat flying in front of me after an alcohol withdrawal seizure?

I had an alcohol withdrawal seizure. Since then it seems like a gnat is flying in front of my right eye. Is that normal?

No, it is not normal to see a fly (vitreous floater) in your vision. The sudden occurrence of vitreous floaters can be the first sign of retinal eye disease or retinal tear that could lead to a retinal detachment and blindness. I urge you to see your ophthalmologist as soon as you can to make certain you are not at risk for any of these unfortunate events.
