I had the same issue?feeling my heartbeat. My heart would also start to beat fast just standing from a sitting position. I would get dizzy. Of course, this can all be traced to symptoms of mercury.

Whoops, I did it again. I had salmon.

Went out to dinner the other night and did the unusual (for me) and had salmon.

That night was a difficult night for sleep as it felt too cold when the covers were off, too hot when they were on. Reminded me of the old days. Without the Algin I took, I can only image what kind of night it would have been.
