I went thru the list and didn't see any commentary on this one. So....anyone out there ever try Lithium for migraines or clusters or both? I have literally exhausted so many classes of drug preventatives and currently am on Zonegran after being on Topomax which I think the Topomax was working better but both are failing truly. I've been holding out(years) the dr wants to put me on Depakote which the side effects look worse than the migraines; then he says there's good ol' Lithium. Like has been around forever to treat serious mental health issues which is fine....if it works...for MIGRAINES...Anyone?? Side effects? I get how almost all our preventatives have not been created for migraines but sorta work on them(ha ha) anyone have any luck on this one?
