I am 55 years old, and was doing a few things around the house this morning, when I began sweating horribly, and could not get it to stop. I normally sweat when I do strenuous things, but this was extreme! My shirt was drenched, my hair was wet. I felt exhausted, so I sat down and took a drink of water, from a new bottle I opened at that time. The water tasted sweet, like sugar water. Should I be concerned?
