Expired goods expiry date January 2023

Expired goods.i bought expired viral+ from Checkers on the 26th April 2023and I feel bilious every time I try to eat something and have constant headaches. I vomited a lot before I discovered that the FIZZY TABLETS HAS EXPIRED. I have to take allegex all the time because I feel like vomiting. Checkers replaced it and refunded me but that does not fix how I feel.is Mcnabs merchandisers responsibility to make sure they check expired items
