Yesterday morning I woke with abdo pain and I knew I was going to throw up. Felt rough all day.

Last night hardly slept. Was shivering, sweating, still in pain. This morning came downstairs and began dry heaving, then the bowels wanted in on the act.

It was then I knew this was caused by gluten, but I'm really careful (spoiler - I screwed up), had not been out, not cross-contaminated.

Went through what I ate two days ago and found the culprit.

Tesco Sandwich Pickle. (1/2)
