Some success with GI issues

I posted this as a comment but thought it might be more broadly helpful.

Out of the blue I developed abdominal pain and changes in stool in the second six months of post Covid. MRIs showed nothing and a stool analysis was clear. On the suspicion of bacterial infection, I took Zifaxin for three weeks, which knocked down the abdominal pain by 50%. I then started taking Nortriptyline before bedtime, a "gut relaxer" (my term) which mostly eliminated the abdominal pain, but seemed to allow acid reflux and GERD-like symptoms (burning in chest and racking cough). I added twice daily Famotidine, a prescription strength Prylosec, and stopped eating 3-4 hours before bedtime.

I am feeling a lot better. FWIW
