Anyone taking Omnicef, Probenecid and Flagyl?

Our doctor has decided to try a new approach with my wife and myself. We have been doing the Doxy/IV Rocephin thing for 3 months or so with some improvement. When my Rocephin treatments ended, I noticed a downfall pretty quickly. I didn't realize how much it was helping until it was gone. After attending the Illads conference a week ago, our doc came back with a different approach that he thought would work for us. He starts out with a combo of Omnicef and Probenecid and a week in adds Flagyl. Anyone tried this trio of meds and what are your thoughts?

Also, we are taking our 4 year old son to Albany on Nov4th for evaluation after also testing + for Lyme. Please wish us luck with his treatment. We are completely devastated with this, and hope he can knock this out as quick as possible. As bad as I thought it was for me to be going through this, I can't believe my entire family has to. Hope you all are doing well.....Jeff

The Flagyl was pulsed for 5 days, every 3 weeks.

Omnicef was a little easier on my kidneys than Zithro.

I have no idea what Probenecid is.  Probably you haven't had responses because you're looking for someone who is/has taken all 3 at the same time.
