How about this idea...
Jane,
I may be making some unwarranted assumptions but, if you have three kids is it an accurate assumption to say that you are married?
If so, then how about amping up the sex life with hubby? I am totally serious. I have heard when people quit drinking they have much more energy and this would be a great way to burn off some energy and be edgy at the same. Speaking from a man's perspective the husband probably would be quite pleased by such a positive change.
If you are not married, then sorry for my erroneous assumption and it is probably wise not to go down the path of having intimate relations with people you don't know well. That would be bad for the family, dangerous to your health and emotional well being and could develop into another unwanted addiction.
sincerely,
jack
