I have been on gabapentin for 3 months now. I take 300mg 3 times a day. I was prescribed this medication to prevent migraines. It works well and I tolerated it well when I first started taking it. As of last week I have been dizzy every day. I know that dizziness is a common side effect of gabapentin but is it normal for a side effect to take over three months to start? I am just trying to figure out if my dizziness is related to my medication or if it is something else all together
