Sure you have. The little inflamed, white bumps on the tongue that hurt like a sombitch?
Well, here's the treatment, as unlikely as it sounds.
Get some liquid Maalox, Mylanta, etc, and some Children's liquid Benadryl (store brands, as pictured above are just fine, and cheap -- that stuff above cost under $5, tax an' all). Mix it 50/50 in the little cup that comes with the kid's Benadryl, and swish it around in yer mouth. 60 seconds later, spit it out.
Repeat as needed. Don't swallow it unless you wanna go to sleep (Benadryl affects many people thataways).
