@jkiemen Thanks for replying. Fatigue is an understatement, laugh. All the best with your scans in March Jo Ann.
I saw my doctor yesterday and my blood tests show my thyroid T4 is down -- I have hashimoto's hypothyroidism. This is probably making the fatigue even worse. We're waiting 3 more weeks to do another test, then if it is still down we'll increase my usual dose of levothyroxine. It's the Rifampin/Rifadin that does this -- but it can be fixed with dose adjustment of the thyroid meds. It shows how important it is to get your thyroid levels checked while on the big 3!
