@peach414144 Hi, Peachy. I went through the same thing. Except that mine beat at 153 off and on for days at a session. This lasted about two years, then started getting farther between episodes. Even now I have a few minutes of 153 occasionally, but I can usually stop it by tensing up my whole body for a few seconds. But sometimes it lasts longer.. Me,too, found a med that worked.
