I have a box of the International Delight single serving liquid creamers and used it in my coffee last night but never realized the box had an expiration date of Sept. 2015. I had a large cup mix with 7 creamers, sugar, and milk. Morning now, stomach bloated and aches. Ate a bunch of bread to help soak it up. Any additional things I should do to heal myself? I did toss box away...
