underactive thyroid
"Just diagnosed, my TSH has been in the 20s-30s, my T3 and T4 are at the low low range.  Doctor says I have subclinical hypothyroidism.  I refused the medicine for a month, lost 15 pounds, ate healthy, exercised, quit smoking, and was perfect.  Unfortunately, TSH did NOT change.  Started the medicine -- felt euphoric first few days.  Around day 5... I felt like something was "coming back".  A feeling that I lost 11 years ago when I was 18yrs old (something I gave up trying to fix when I was 20yrs old).  I'm excited by the possibility that perhaps it was my thyroid and I can treat it now. Eager to see how I feel in a couple months!  I think I need more than 75mcg.  I have no side effects at all."
