Hi Sunflower, I had the same response when starting rifampin. Echoing Garzie, at least in my case it was definitely a herx. The nausea and sudden fullness after a few bites subsided after 3-4 weeks. Oatmeal and soups/broths for all meals and increased digestive enzymes to keep digestion easy. It felt like all my body's resources were dispatched to detoxing and there was nothing left for digestion. Same events when I doubled Rifampin. Rifabutin is supposed to penetrate tissues far better than Rifampin so this could explain a deep herx.
If my memory serves me you were on Rifampin before but if not CWL's rec is worth considering. Anxiety and depression are side effects of both rx on top of the disease.
