MOVE!! and drink! Fluids and exercise really help, even though she doesn't feel like it, I'm sure. You need to think about this as a long term problem, so keep up the fiber, fluids and activity level every day. My accupuncturist suggested lightly steamed veggies like broccoli, snow or snap peas and other high fluid foods. It drove me crazy when I was pg and complaining about this to hear how common it was, why didn't anyone warn me???
Other things no one warned me about: the end of first trimester, beginning of second is a bad time for UTIs (bladder infections). Watch out for signs and symptoms, because they can be a serious problem. And maybe start mixing your prune juice with cranberry juice now!
Good luck everyone!!
