Interesting you are starting all 3 at the same time. When I started the big daily I just did the Azithromycin for the first week then added the Rifabutin week two and Erythromycin week three to help determine if any caused initial side effects. Are you also taking a probiotic in addition to the kefir? I did space mine out through the day and for me, I tolerated them better with food even if it was just toast or crackers. It does seem early to add in the IV after a month as it appears to be given if you don’t convert to negative after a longer period, 4-6 months. Hope you tolerate the meds well, sorry you are going through this journey but glad you found this group which is a great support and resource.
