How to effectively use gabapentin?

I have 500mg Gabapentin and I was just wondering what would be the best way to utilize it I’ve never done it before but have some experience with other gabaergic substances such as benzos and alcohol and I also know it doesn’t necessarily work for everyone also find it kind of strange that it is a controlled substance in my state but it isn’t in every state

Like do I take it on an empty stomach?

How much should I take? I only have 500mg
