my dr put me on a dose of 400 mg gabapentin once daily before bed. I have been on it for almost a week, and I am shakey and dizzy, I keep getting dark spots in my vision when I stand up. I called my dr. yesterday for that, but this morning I woke up and I feel like my legs are weak and im having a hard time walking. I called my pharmacy and they said to stay on it for another week, and see how it goes, but im kind of worried about why I am feeling this way, it seems kind of dangerous to have my legs go numb and to have a feeling like my legs are falling asleep
