Zithromax is in the same family. They're both pretty good for Lyme but Biaxin may be a little stronger in oral form. I get a ton of OCD as part of my herxing anxiety also.
I wouldn't say Biaxin is stronger than Zithromax, it's just different. The lipophilicity of a drug determines it's concentration. Biaxin remains in the blood much longer and has a much higher blood concentration than Zithromax, but Zithromax has a much higher tissue concentration. Lyme lives in the tissues but also in the blood. Neither is overly effective at Lyme harbored in biofilms.
