I cannot find the past threads on this, but I know we discussed it. I am having a "flutter" in my chest for the past 3 days. It only happens at certain times, and it doesn't last that long, but last night, I couldn't sleep for it. Didn't someone say that fish oil could cause this? It doesn't happen right after its ingested, it varies day to day. Current dose is 3X day. 3000mg
