Antibiotics are just a precaution anyway, the nurse told me that on discharge. We also do the same for dental implants, it’s not essential if you know what I mean. If they are making you so ill then sometimes they don’t help much. I stopped mine after day 3, I stopped absolutely everything because It was all making me very poorly. Cut down to ibuprofen and I was fine by day 5. Listen to your body, you know best! Xxxx
