After surgery for a goiter with numerous nodules, I was started on 100 levothyroxine and felt fine. Due to too high TSH level (10+), dosage was increased to 150 and I went to the other end of the scale (.45). and the dosage was lowered to 137. Now my GP has reduced to 125 due to fatigue and depression. Have been at that level for 2 weeks and still have some depression and insomnia. Should I seek advice from my endo?? or keep waiting to see if these symptoms subside. It obviously is not easy to wait but don't want to compound the issue.
