Underactive Thyroid
"been on levothyroxine for about 5 months. initially 50mcg. After about a week or two, I immediately felt better. &quot;brain fog&quot; was decreased, I felt Alot less tired, a lot less cd. also, I lost a significant amount of weight (I put on a lot due to an undiagnosed autoimmune thyroiditis). I&#039;d say the worst side effect of this is the massive hair loss initially. and my hair was tangled so easily. I am now on a maintanence dose of 100mcg. have bought myself a decent hairbrush and I feel a lot better."
