These antibiotics damage the mitochondria, which leads to rapid aging and worsening of any existing conditions. There is a protocol to help them recover, I've found it difficult as it causes relapses.
Nicotinamide riboside is one of the supplements.
My symptoms were post-exertional malaise, full body neuropathy with numbness, burning, and tingling; my spine and all other joints developed pain from the damage to cartilage; more cognitive impairment than I had with Lyme; and my skin has visibly aged, with lots of fine wrinkles and deeper cracks in existing ones.
