Binduspire,
I've just noticed that you didn't get a reply on your post from August 4th.
I don't know the exact dosages of Clarithromycin and Amoxicillin, but I think it's safer and better to handle to build up dosage. The die-off of the spirochetes can make you feel very lousy (Herxheimer Reaction).
Please be sure you detox enough! You can find lots of info about detoxing in the 'New to Lyme?.... Start here!' thread. Very important to detox, your body needs to get rid of the toxins...
Good luck!
