I hear you, Stacy. I feel the same way.
The side effects from the methimazole are relatively infrequent/i.e. rare. I think — but don’t hold me strictly to this number — it is something like less than 5% of people show up with any significant side effects. I would suggest that you talk with your pharmacist: he/she would be the best source of information, and there’s probably a print-out you could take home with you.
Being tired goes hand in hand with both hyperthyroidism and the hypothyroid state. But the dose that you need of the methmimazole has to be calibrated to your needs specifically, so it is possible for it to make you hypo. I could feel a difference in the type of fatigue I had while hyper or hypo. If I exercised a bit while hypo, it energized me. (I’m talking a quiet walk, or something simple, not kick boxing or spinning.) If I tried even a quiet walk while hyper, it only made me more tired. Also, if the medication is slowing your body down, as it is supposed to, you could be feeling just how tired hyper was making you. Without the added “jazz” of thyroid hormone, we do feel fatigue until we readjust to “normal” again.
Since your kids are ill, make sure to wash your hands, wash your hands. It isn’t just the medication that you are on possibly messing with your immune system, but you have been ILL yourself. Your resistance might be lower because of the wear the hyperthyroid state has put on your body.
