It can be pretty rough when you are starting out, that's for sure! If you are just starting treatment, or if you've never been up to the required amounts of abx (* see below), then it's just the 'cycles' that the bacteria normally has and each infection has it's own schedule.
*For a general idea on what abx at what dose is required, please read Dr. Joseph Burrascano's paper, Advanced Topics in Lyme Disease, which can be found in our 'New to Lyme?' thread, and here:

Also, be sure you are detoxing, dry skin brushing & drinking
lots of water, as those toxins will overwhelm your body causing even more issues, even if you aren't on abx or on a high dose of abx!!
