Hi Bansaw -
Sounds like you're getting a great start. YES, a herx might include fatigue and aches - sounds like a normal response and manageable herx and if might be good to push through it.
Generally, as you lower the microbial load with the herbs, the herxing should subside or come-and-go. You might want to try to increase detoxing to make sure your body is able to process the toxins and treatment effectively and to prevent what you're killing from getting "stuck in the body" as debris and toxins, which can create symptoms.
If the herx gets much worse and intolerable, you might want to take action like increasing detox and/or reducing your drops, maybe take a day off.
Keep up the good work!
