About 8 months ago I was given about a whole bottle of Delsym. It was poured into my drink without my knowing. I got a terrible headache and eventually passed out. The next day, I experienced many vision problems. Whenever I look at lights, they are very hazy and look like "starburst lights" and they have a glare to them. My regular vision is fine, just lights are terrible. Oncoming headlights and stoplights are completely hazy and I can't stand it. I went to my eye doctor and they said nothing is wrong. But obviously something is wrong. I also have a constant ringing in my ears and I have since 8 months ago. And lastly I have many muscle spams all over my body. It's nothing huge they're just like little muscle twitches, but they occur a lot and it's very annoying.
Does anyone have any ideas as to what is wrong with me/what I should do?
Any answers appreciated,
Thanks.
