And I would advise against it. I took this over an anxiety of mine that I had either Lyme or some bacterial infection that was causing pois. I had this anxiety for the longest time and now it's gone. I did not feel any worsening or improvement of symptoms. Only how I usually do on antibiotics which is slightly anxious. So this tells me, along with negative blood tests, that I don't have a bacterial infection at the center of this.
But coming off doxy was terrible and I had pain, in my lower gut, eating anything for a week, and did experience pois twice. I messed up my gut and now supplemented with natural probiotics such as sauerkraut. Pois seems to be getting better now and I am slowly going back to my non pois self.
So I'd definitely advise against it. It could take a while to heal from 3 weeks of doxy. This tells me that the health of my gut is very closely related to if I experience pois or not.
