Last week, I ate a can of tuna that was opened in the fridge. Thought one of the kids had opened it but found out later that noone knew how long it was opened for. My first fear was botulism. Now a week later, I have been running to the bathroom for 2 days (probably IBS) but can't get my mind away from the botulism thing. I am sure I would have shown signs before now...I hate feeling this way...The logical part of your brain telling you it is nothing to worry about but the rest of your brain living in dread...
