Hi bigdaddy, Get a good thermometer. A glass mercury one will be most accurate. I wasn't able to find one localy since they are being banned. I got a digital one for about $10.

Keep the thermometer by your bed and when you wake up take your temp before you get out of bed. Take it again every 3 hours. Average the first three temps and if the average is below 97.9 your metabolism may have slowed down or you may have a thyroid system problem.
