Hi Stacey,
        I have been taking Synthroid for approximately one month and feel
better than I have in years (I have Hashimotos).  I still tire easily
at times and have also lost _lots_ of weight (10% of my body weight)
in this same amount of time.  This could be why I easily tire...
        I would like to get (and stay) pregnant, my endo says being pregnant
increases need for thyroid hormone, so I would get a blood test to
check levels.
        Good luck, Marlene
