Hello,
I was on Methimazole five years ago and I am 46. It helped keeping the blood work within the acceptable level, but physically I did not feel a vast improvement. Perhaps it was subtle. I was on 10mg a day and it got cut back to 5mg a day. I gained 45 pounds from the medication and once I was off the medication, the weight started to come off. The blood work came back normal. I took the medication for 1 year and I am not on medication for Graves’ now. I still see the endocrinologist every year. I was tired too and I had the brain fog. These problems were especially pronounced near the monthly cycle. One thing that helped me was to take an iron supplement for few days right before the cycle and during. Otherwise I had trouble getting out of bed. I would sleep for a long time and when woken up, physically I had trouble moving. This is difficult to do but I found being on paleo or whole30 really helped me physically. Admittedly these programs are hard to keep up and nutritionally I have to make sure I eat foods that are good for me and take a multivitamin. On these programs, choices of food can get limited. I do cheat occasionally with smaller quantities, and I still see a big difference in how I feel. Everyone is different, but for me, I believe this is the reason why I was able to keep the blood work normal without the medication. I found a good decaf coffee and this helped me lower my blood pressure and the heart beats.
For the sleeping problem though, an iron supplement was what I took for a few days. I would see an improvement within a couple of days.
