Case A: A 45YearOlds Story
Maria (not her real name) began a 30mg regimen after years of feeling sluggish. Within three weeks she described feeling like I was on a caffeine binge without the coffee. Her primary care doctor reduced the dose to 12.5mg, and her energy steadied out. She now checks her thyroid panel every six months and feels back to myself.
Case B: Reddits hypothyroMike
Mike posted on r/Hashimotos in early 2025: I cranked up to 60mg to hit my target TSH and woke up with hair loss and a racing heart. Dropped to 45mg, hair grew back, heart calmed. His experience highlights the dosedependent nature of side effects.
