Do you think Lyme Disease has a definitive cure?

What antibiotics are you taking? 

Doxicicline, cefuroxime, minocicline, tetralysal and ceftriaxone

I think you can have multiple infections. A good doctor will test for other bacteria that may need different treatment concurrent with your current treatment.

repair enzymes. never use antibiotics.

If you're been on antibiotics for that long with little to no improvement I think your doctor should be looking for co-infections such as babesia, bartonella,  anaplasmosis,  etc. A good lyme literate doctor should be able to examine your symptoms to narrow down the list of what co-infection to test for or treat for.  For example, I have lyme with babesia (blood test positive for babesia ducani ).  I need to take heavy courses of anti-malarials as well. Antibiotics alone will not help me to get better because I have an active co-infection.  Antibiotic are important though,  and they do play a massive role in treating lyme, but supplements, herbs, vitamins, and minerals should also be used to support the body's systems and organs to facilitate healing as well.  There's no single definitive cure for lyme.  It takes a lot of effort and a lot of different things to get well. It's a journey, but you can get better!
