How long does it take for the side effects of doryx (doxycycline) and will my bod adjust?

Probably will: Doxycycline is an antibiotic in the tetracycline family that is used often for spirochete illnesses, by far the most common today being lyme's disease. Often it is given preventively if there is clear exposure to a tick that got it's fangs into you and couldn't just be flicked off (this is appropriate). Don't take it with food, definitely not milk, and if mild side effect, stick with the course.
