All I can say is I ordered pot roast from Cracker Barrel Saturday night. Ate half. Later started feeling a little dizzy and went to sleep (I’m on a weird sleep schedule right now for work and was trying to stay awake so thought it was that.) An hour later way dizzier, throwing up, headache, stomach cramps. Still not fully recovered. Sad thing is I have beef in my freezer from a quarter cow I purchased and had raised with nothing added to it. Just being lazy after 12 hour work days and finally some time off.
