I do, and my lyme doc does not have any complaints about it.  On one
occasion he prescribed me an herbal antibiotic and it didn't have any effect
until I added CS with it.  Then I broke out in bumps all over my body.  Not
sure what it was, but I am glad it died.

There is also a silver compound product called ACS 200 which is going around
in the lyme community and docs are using it with antibiotics.

An in vitro study (not in vivo) showed a certain silver product added on to
the effectiveness of antibiotics most of the time.
