Yeah absolutely. So I got prescribed the device by my neurology. I didn't have to pay anything and have had three top ups so far. You get a 93day card with the device and it will run for the 93 days and then stop working. I just email my neurologists secretary and she sends a prescription form to GammaCore and they send out another 93 day card and lubricant. I haven't had to pay anything for this which is something I'm grateful for.
So you can use it in two ways - as an abortive (3 x two-minute stims, 3 minute wait and then 3 x two minute stims) and as a preventative (3 x two-minute stims in the morning and 3 x two-minute stims in the evening). I was mainly using it as a preventative and I think it might have reduced the intensity or attacks but didn't get rid of them. There was some residual nerve pain / sensations afterwards for about 5-10 mins I guess I could liken to shadows in intensity but running up the nerve in the neck and head. It's difficult to say how benificial it was as it's something I'm still experimenting with.
In terms of using it as an abortive I stopped using it for nocturnal attacks as they were always so well developed and I found it didn't really help with the pain and if anything agitated them more so. I use as an abortive for some attacks I get during times I'm awake and again although it doesn't get rid of them I almost got the sensation that it was spreading the pain out over a larger area and so it almost didn't hurt as much as the pain was spread over a larger area and so hurt less even thought the pain didn't really dope. I hope that made sense but I always find my CH feels like a nuclear bomb has gone off inside a single cell.
In summary I'd say I'm sceptical about it's effectiveness but it's definitely something I'm gonna continue with as I really haven't used it enough so say either way. I hope that helps, let me know if you want to know anything else.
