my husband's job changed tremendously because of the intensity of the last two hurricane seasons; he was gone A LOT.
On his first stint, it was very very stressful for him and being the good wife, I was in a dither about him.. so i had a lot of abdominal pain. The dr put me on some sort of antiacid for 1 month and i got better.

So plain old stress can do a lot of damage!
