My periods have never been regular. I'll skip months and then when I finally do get it - I'm usually in a lot of pain for the first few days at least. The only thing that helped before was going through bottles of Midol, which would usually take hours to kick in at first. I did a lot of research on Livia before treating myself to the device over a year ago - and I'm so glad I did! The relief is practically instantaneous when you turn it on and I love that I can wear it anywhere. Of course on bad days I can have it on high and still get twinges of pain but it's nothing compared to the pain without the device. Best purchase I've ever made!
