I have the VNS!!!! I was implanted with it in November and turned on in December 2006. It is called the vagus nerve stimulator, it is a pacemaker-type device that is implanted where a pacemaker would go. they then make an incision in the neck and wrap the wires around the vagus nerve. For me I am thin so it is kinda ugly where the wires are because you can see where the wires are laying under the skin, my incision for my device is healed but you can see the impression of it and feel it that is too because i am thin.
I really think that it has helped me because of all the stuff i am going through. I actually only take 2 meds as opposed to 5-6. I have some discomfort and side effects with it but all in all it was a good decision.
It is extremely hard to get this covered under insurances right now, i was able to get it (i did fight really hard for it) because i have narcolepsy as well.
I would be more than happy to give anyone info if they would like it, i think it has changed my life
