I too have PVC's and I understand how annoying they are!!
Have you tried magnesium supplements?
Quite a lot of people who have pvc's use magnesium and have great results with it!!
It didn't work with me but everyone is different!
I'm trying Taurine at the moment and I'm sure it makes the pvc's less intense!!
Also have you tried a beta blocker?
I can't take them as my resting heart rate can get low.
Hope u find relief soon
