Hello. 3 days ago, I had a short-lived stomach virus,around 24 hours long, and vomited a total of 21 times, causing me to lose some weight and become dehydrated. Ever since then, I have had this continuing bad taste in my mouth. I tried drinking a lot of water, brushing my teeth and tongue constantly, and using mouth wash, but it doesn't seem to work. Originally, the bad taste originated in the left side of my mouth, along my tongue, and now it has spread to my entire tongue. I thought it may have been oral thrush, but I saw no film or change in my tongue's appearance.
