This Year's 1st Food Poisoning Episode

Guess it was bound to happen sooner or later, as me and the digestive system haven't been in good relations over the past year[s]. So it's now.
My efforts to try and take it easy over the holidays seem to have paid off, too bad though that less than 3 weeks into the year the status quo's been challenged.
And I still can't tell what it was that got me here. And I wish my face stopped itching for a change.
Lessons [to learn]: no meats [oops!], no aubergines [oops!], just plain rice & potatoes. Looks like I got it all wrong again. For 3 days now.
