At 29, She's Still Bed Wetting Please Help Her!!!!!

Hello my fellow Nairalanders, my girlfriend has been suffering right from her childhood till now, please is there any solution for her because this bed-wetting issue is becoming something else. just yesterday she decided to spent a night in her boyfriend house since it was raining heavily ( note, she doesn't sleep outside because of this problem) only for her to come to my house this morning as early as 5:30am with tears in her eye and when I ask her what happen, she told me the same old issue of bed wetting and that the guy drove her out, call her names and ask her never to call him again.

please what can she do to stop this mess because age is no longer on her side.
mature advice please!
