Doxy does not treat Babesia as well as antimalarial meds can, from what I understand.
Are you communicating with your doctor how badly you feel? What does he/she say?
There are strains of Lyme that are resistant to Doxycycline, too, so maybe you need to discuss alternative abx with your doctor...
Also, I agree with the others in that detoxing should reduce symptom severity. Milk thistle does not detox the brain...I know Dr. Jernigan's formulas are able to do this...
Good luck & take care,
