Started naturethroid about a week ago, never had any thyroid medication despite having TSH of 7 / 8 for over 7 years. Started on 30mg, then after 4 days, alternated 70mg and 30mg, so on this for a couple of days. And I already feel I have more energy, don't need so much sleep (up to 14 hours a night) and chores that seemed so daunting only a week ago, seem quite manageable now. So is it possible to notice an improvement in such a short space of time?
