First Rash

It was 8 years ago...
After 2 or 3 months I came here United States...

By the time I felt I got used to American food, big portion of meal, coffee & bagels,
I started having rash night time...every night.

First I thought it might be bed bug.
But even I slept other places, I got the same symptom.
I was taking antihistamine to stop it.

I also started gaining weight around the same time.

And then I got around 20 pounds in 3 or 4 months,
it stopped suddenly...

I still don't know why.

But this was not the end of my struggle with allergy...
