Ate the Super Sub at 12 noon (Ham, Provolone, etc) made 'Mike's way' - no onions). Felt a little 'full' all afternoon. Did not feel like eating dinner. At 8pm had diarrhea almost non-stop for 10 hours. Had nausea which i 'willed' myself not to vomit. Was getting a little better by late morning the next day. Only other thing i ate all day was a Starbucks cappuccino.
Stomach flu by sheer coincidence? or food poisoning - I am not a doctor - but that's what happened.
