I’ve run out of options, and I’m becoming very skeptical of all these medication’s in there long term affects on my health. I found out about this while researching devices for headaches and it’s been very very helpful. I’m very shocked at my neurologist never even heard of it, but was willing to send in a prescription for me. I guess we’re all they do is push drugs at you they don’t get to know about these things. I’m now using this instead of breakthrough migraine medication when Botox doesn’t cut it. I will have to see how this works when the Botox wears off and things get really severe. I suspect it will work just fine I hope.
