Burning bands of hot acid.

I was miserable most of last night.  I think it is because I made some cookies with brown sugar and ground almonds.  I had eaten roast beef with gravy and diced tomatoes earlier.  I assume the brown sugar was the main villain, although the ground almonds could also be implicated.  I tried to take various remedies but ultimately fasting and taking salted water today has improved my situation.  Tomorrow I will probably eat salmon with lemon on it.
