Hi,
I'm sure the good Doc. RLR will explain to you better what is going on but I'll share few of my experiences to help you feel better.
In my case a few glasses of good red wine do miracles to my PVC's - IT MAKES THEM DISAPPEAR! Like a magic wand - they are gone! It last until the wine wears off and than all starts again. I'm not an regular drinker but I like to have wine with my dinner. If I drink more than usual tho I'll wake in the mid of the night and my heart will race like crazy. Very uncomfortable. I usually take a couple of Valeriana pills and goback to sleep.
Also, I don't feel my PVC's at night, they doesn't wake me up but at the moment I open my eyes, 5 min later they start like someone switches them off! Very frustrating.
I also have those episodes of not being able to take a deep breath most of the time I'm alone. All that is anxiety, I know. I try immediately to occupy my brain with something and than voila - I'm breathing normal again!
I'll advise you, if you have ruled out an underlying health problem, to visit this forum and read it as much as you can - it will help you tremendously!
If RLR don't mind, can you please tell me what the wine have to do with diminishing the PVC's completely for a period of time and why when I wake up free of PVC's they stsrt again 5-10 min. afterwards?!
