Thanks! I did mean gabapentin. I was also on a vitamin mix that had some stuff in it that might have also caused the heart issue ( 7200% of your daily B6 needs definelty wasn't helping). It was an intense scary night. My heart was racing but hardly pumping any blood. I probably should have gone to the emergency room but didn't want to inconveince my wife. Now it seems silly but at the time thats what I thought. I had an ekg which turned out mostly normal (normal from what it showed 9 years ago anyways). I also wore a holter montior for 2 weeks to capture some episodes I was having ( which was coming from taking zinc carnosine, a stomach supplement) but still haven't gotten the results back. I see my doctor this week, I just wanted to be prepared cause he is pretty lost in trying to treat me just like all the doctors I have seen.
