Shut you up? I'm not sure why you mean. Also, yes you cannot just stop it or go off it without side effects. It also depends on your dosage. If you are only taking maybe 100mg you may be able to but if you talk to any Dr. or pharmacist they will tell you to taper off it gradually to avoid side effects. I actually know people who have just stopped it and there can be side effects from doing that which is why it's recommended to taper it. Yes it was originally for people who suffer from seizures but is also used for nerve pain and it does help some quite a bit. I have no neck pain anymore at all and it help with the sciatica in my lower back. Many drugs have off label uses like Gabapentin and your body can get used to it just as it can pain meds which should not be stopped suddenly either if you have taken them for some time. Google Gabapentin and you will see all of what I have just commented and much more.
