I ocassionally get double vision. It has brought on major anxiety issues and I am puzzled at how I can prevent it. I can watch the double vision move across my eyes and when I drink a bunch of water and calm back down I can actually watch my vision slowly come back in about a half hour time frame. I have to drink a ton of water every day and if I go a couple hours without water I start having vision problems. No one can tell me why this happens. I have had my thyroid checked twice, tested my blood sugar on a regular basis, and even had blood tests done on my kidneys, had a cardiologist monitor my heart and a CT scan of my head only to be told I am completely healthy. Only now I am getting scared to leave my house because I never know when it will happen and I have this fear of what will happen if it doesn't go away next time.
