Levoxyl and endocrinologists

I am so glad I found this site! Start on Levothroid 100mcg 3 weeks 2 days ago. 1st day - Felt fine... 2nd day - horrible headache starting over my eyes going straight to the base of my head. 800mgs of ibuprofen to dull the pain, never stopped, just dulled. I was lethargic and slept for about 3/4 of the day. Day 3 - same issues. Day 4 - I did not take, felt better but still exhusted. Day 5 - 19, 50mcg of Levothroid: still felt very tired, but mainly I was becoming more and more aggrivated by little things... Things that had never bothered me before! I would think about smacking people or popping them upside the head for stupid reasons. I was getting so upset for nothing - all the time. Day 20, stopped for the day. Day 21, took 25mcg... boy I felt so much better. No where near as cranky! Endocrinologists claimed the meds weren't the problem. Saw my G.P. on day 21, he agreed the Levothroid dose was way too high and prescribed me the 25mcg for now. Says in a couple of weeks go up to 50mcg and see how I do. Thank goodness!
