Levothyroxine
"I've been on levothyroxine since I was about 16 (I'm 38 now).  I stopped taking it in 2005 and found that my after plucking my eyebrows they didn't grow back.  I had hair loss, fatigue, mood swings, everything you can imagine....I had it.  I am now going back on the dose I was on prior to stopping which is 325mcg's.  I know it's a lot but my thyroid is so off the charts they need to ramp me up.  I'm hoping I won't feel so tired and bi-polar after a few weeks of being back on the medication.  I'm not really clear on why I stopped taking it but I'll be happier for being back on it."
