When is it worth getting VNS

I've had epilepsy since I was 6 and am now 30. I've tried many medications & I've had many doctors due to them moving to other states. My current neurologist is the only 1 to mention the VNS. For Those of you who've gotten the VNS, was it because you had the more severe seizures. I have absence seizures. I'm conscious, but stare and blank out, so I'm not sure what another person is saying to me until I'm out of the absence seizure which lasts anywhere between 5-30 seconds. Example: I'm going down the stairs, have an absence seizure so I know I need to stop going down the stairs until I can see again. Sometimes at work it's a little worse where I have absence seizure every other minute so I need to go sit down for awhile. Working in customer service kind of sucks because some people really stress me out, most likely causing those seizures. I don't get an aura so it's unpredictable when a seizure will come. So what I'm really trying to get down to... Do you think it's worth getting a VNS when I have absence seizures? I think the main benefit would be if I don't get absence seizures anymore I'd be able to drive. Anyone's opinion is greatly appreciated!
