Hi lifedancer,
Welcome to the forum! We're so glad you found us:) I love your nickname by the way.
This is just my opinion. I am not a doctor and this is only from what I have researched but you should be on at least 400mg of doxy for a new infection. Did you ever get a rash at all? Most people don't get a rash or even know they were bit. I am just curious.
Since you are having all those symptoms, I'd ask your doctor to increase your dose....just to be on the safe side.
Here is some information on dosing and Lyme Disease.
>>Dosage:
Increasingly, clinicians recommend that certain drugs used for Lyme disease be given at higher daily doses: for example, 3,000–6,000 mg of amoxicillin, 300–400 mg doxycycline, and 500–600 mg of azithromycin. Some clinicians prescribe antibiotics using blood levels to guide higher doses. Close monitoring of complete blood counts and chemistries are also required with this approach.<<
