I tend to get an arrhythmia, PVCs. How long can you go without much (or any) protein, before it starts affecting things. I've not been drinking much, at all....approx. 30-40 oz. liquid. Every other day maybe 30 gms protein...some days none. I started getting some PVCs....obviously, lack of nutrition. (and can't eat, due to the esophagus issue). I'm holding on, until I see a GI doctor, this Tuesday. The pain and vomiting had become more than I could handle.
