I'm sorry to hear of your symptoms including having had COVID. I thought I was going to have to live with all of my symptoms which also included several hours of lost sleep b/c I couldn't digest the food I was eating. I had been on PPI's and famotidine for many years. After developing a rash over quite a bit of my body, my doctor removed PPI's from my medications and added Carafate. When Famotidine was found to be linked to possibly causing cancer I was switched to Ranitidine. But since I started the enzymes, I am now sleeping and am slowly decreasing my Carafate and Ranitidine dosages. Hopefully I will be off of them soon!!
