Good old food poisoning

Not sure if this is good poisoning but this has happened to me twice in my life with no idea what caused it. It starts out with me being backed up for a real long time. After about two weeks the flood gates finally open. Then they do not shut. I woke up 4 times a night to poop. I’d leave for work early so I don’t get stuck in traffic and crap my pants. Get to work and go 4 times in the morning and go 3-5 times in the morning then things would calm down after lunch. Repeat every single day for two months. Serious diarrhea for two months is a terrible terrible thing.
