ahh yes, those positional
PVC's...
mine are worse when I lie on my back. And you know what is really wierd...that yoga breathing...if I try it...breath in ...breath out... it makes them WORSE! Also when I slouch after drinking water..they seem to worsen and I have to stand up to make them go away. Don't worry....this is a commen problem and is totally benign.
