I was on Doxy for 8 months then was taken off of it before I started Flagyl. I have taken other meds along with both of those but never took them together. I don't know alot about the meds but 2 weeks seems very short! I was under the impression that each antibiotic needed at least 3 months in our systems to be effective?!?! Also, I had a horrible herx after starting Flagyl, so maybe that is what she means about if you do not have a reaction?? Although I am not sure if everyone does herx with Flagyl. I have heard some do not!
Sorry I am not much help.....
for the record, i don't like drugs either ;-(
