I was diagnosed hypothyroid earlier in the year, started 50mcg thyroxine and felt instantly better, lasted about 3 months before I started feeling like death again. My numbers don't look bad at all, Tsh 3 and t4. 15 but I am so tired, I can sleep 9 hours at night, 3 hours in the day and I'm still tired. Tablets upped to 75mcg 2 weeks ago and drs said they'll up to 100 next week if I'm not better but I'm starting to worry this is just how I'm going to feel for the rest of my life. I'm trying to stay active and eat well nothing is making any difference. Please someone tell me positive stories.
