i have problems with PVC's every day

[k2ll]

i have had PCS's since i was 18 years young, almost normal weight. I have been struggling with them ever since and i have had many blood tests and echo of the heart 2 times. Everything game back normal and my doc said that my PVC's were normal. but those PVC's made me really nervous and anxious person. Last year i made a really big change in my diet and started eating very healthy, salads and stuff and exercising but my PVC's were still daily even with running and exercising. I tried magnesium tablets and iron supplements and so on nothing worked so far. But since then i made a really big change of my drinking habits i had a huge difference. I started to have 2-3 cups of lemonade mineral water every day and my PVC's have been completely gone for 3 months since i started to drink lemonade water. I cut lemonade slices into my water and put it in to the fridge to drink over the next days. I do not have problem with PCS's ever since. I know that lemon has vitamine C in it. Does that has something to do with it?
