Bertarecchia

I'm 43, male, lived in Italy until 28, spent 13 years in DC and NEVER had issues with stomach pains. Lucky enough I never get headaches either! I generally feel great.
Three years ago I moved to miami and since then I started getting these seemingly untraceable, horrendous stomach cramps, at the top of my stomach. They just take my breath away for hours and mostly at night. I have no heartburn or acid at all. I carefully track what I eat so I know what I've had before the cramps start. Once the pain is gone I have soreness in my stomach/muscles just like when you do an exhausting abs exercise!
After months of inability to find a pain killer going through all kinds of remedies/medicines I decided ( in desperation ) to try DayQuil. A heavy shot of it stops the pain in matter of minutes. Niquil doesn't work. Weird uh?
The only common substance / factor is Cuban Coffe. Since I moved to Miami I ran out of my Italian stash of imported coffee so I had to switch to the locally produced Pilon, La Llave, Bustelo. I know it may seem absurd that this coffee could be the problem but yesterday, after my regular coffee in the AM and one heavy shot in the afternoon, I got home feeling the pain coming and as soon as it became strong I blocked it with Niquil.
I usually have a light espresso in the AM and a light one after lunch. That's the most I take.

Any1 else with this problem?

Secondary possible causes by tracking what I eat:
Extra virgin Olive Oil?
Onion / Garlic?
Lattuce with balsamic vinegar, oil, salt?
Eggs?
