Thanks @rmason @irene5 @america for your help. I saw the pulmonologist at the Mycobacterium Clinic in the hospital today. They won't change me to Rifabutin because my damaged liver cannot take it.

They said I will have to just accept what the Rifampin is doing to my thyroid and cholesterol. That's hard because I'm so hypothyroid now I need to sleep almost all day and all night, every day, every month. Like Rip Van Winkle! But I'm not sure how I can accept that for another year or two years. Next week I will see a psychologist for some help with that.

(@america I take my Levothyroxine 8 to 10 hours apart from the Rifampin -- in the morning. I always take the TB meds/Big3 at night, as advised by my pulmonologist. Rifampin doesn't have any big problems for some people with thyroid disease but for others it does. Unfortunately it does with me).
