1) If I were Ill I would have taken the antibiotics of obvious choice, amongst which are Amoxicillin, or the Beta-lactamase protected one Augmentin.
2) If the drugs would be proven to be inefficient I would consult my health care provider and possibly start treatment with Doxycycline.
3) I know that antibiotics should not be taken without a consultation with a doctor, that is why I always visit him, when I get sick.
