Pricey but effective!
I’ve been taking it for about a year. Was forced off for couple weeks when stuck out of town after Harvey storm so able to be reminded - with return of flashes- how much it has helped. Really made the difference in getting good night sleep!  Specifically effective in decreasing intensity & frequency of the “electrical storm” symptoms that would wake me multiple Xs a night for years. Little pricey but so far worth it.
