Gabapentin was a disaster for me. My psychiatrist prescribed it to help with sleep. I had an eye doctor appointment a few days after starting it, and literally could not find the parking lot, even though I had been there a dozen times before. Coming home, I couldn't remember if I got a free turn on the right red light or the left one. I was only driving 30 mph but felt like I was going 60. The next day I was so dizzy I could not walk. I couldn't step down off the curb to get into the car. I had to hang on tight to my husband to move. I quit taking it then and there, and told my psychiatrist my experience with it. She classified it as a drug allergy.

So maybe my experience is totally different from anyone else's. all I know is that I would never take it again.
