I take an electrolyte that does not have sugar - I find most too sweet. I use one by Native Patch - the Berry mix is best. This helps with dry mouth and skin.

I had diarrhea for 6 months and could not take Imodium - made me very sick. I take a probiotic every day and also a supplement - EMMA made by Enclave Bioactives, created by a gastro doctor. No more diarrhea and no constipation. I have been on Tagrisso for almost 3 years.
