anxiety
"Ok, Gabapentin worked fine for me for anxiety.

But I was un aware of the ridiculous side effects it comes with. 

I was 160lb male, which I was happy with.

Unexpectedly I kept gaining weight that I was un aware of. 

From 160lbs, now I'm 245lbs!!! That's 85lbs I gained within just 8 months!! I tried to stop taking it for just 1 day, and I went into SEVERE withdrawal. It felt worse than both opiate and benzo withdrawal!! Stay away from this drug!"
