I'm currently on a 2 month course of Doxy, 100mg 2x a day,
first month didn't notice much of a difference in how I felt, would have nausea sometimes.
second month, 4 days in, when I take the pill I have pretty high level of muscle , joint pain, headaches for a few hours.
how can I tell if this is herx or a side effect of the medication?
Are you detoxing? Do it every day. If you detox and it helps, then it’s a herx.
