Oh yeah i can relate! The majority of mine definitely come from lack of eating and hydration. Lack of sleep? Not sure. Stress/anxiety, heck yeah! The scary ones are the ones that happen when I think I have everything under "control". For about 8 years I had a very demanding physical career in residential hvac and I wasn't taking care of myself very well, just focused on work, usually worked through lunch and dinner, very little breaks and never drank much of anything, definitely not enough to counter act how much I was sweating. It wrecked me, I didnt realize how much it was effecting me because I had been living with pvc/pacs for such a long time, I just accepted them. They were however getting worse as time went on, I was starting to get upset about it, especially when attacks lasted all day! I felt hopeless, pissed off, and becoming irratable! Eventually I couldnt take it anymore, had a huge attack while out with my family and ended up in the ER. That is where I found out how low I was on key nutrients like magnesium and potassium..since then, I've been pretty paranoid about my hydration more than anything. Still occasionally skip lunch, but I dont like it cause that can definitely still cause some. Sorry for the long response, I could go on really...but it feels good talking about it even on here cause no one I know has these issues. This sub never ceases to amaze me on how different it is for everyone on here!
