Hello, I m a 55-year-old man, 5 7 , 250lbs with mild type 2 diabetes. for the past week I ve had a metallic taste in my saliva, mostly from the left side of my mouth. Not constant but very intense when it happens. I generally fast for 20-hours a day and eat one meal. My medications are Losartan-HCTZ 100-25mg, Amlodipine Besylate 2,5mg, Metformin HCL 1000mg (all daily doses) and 81mg Aspirin. Non-smoker, rarely drink, no health issues other than those above and spinal stenosis. Am concerned about metallic taste.
