Lamotrigine reignited my marriage.

 I've always refused meds for pretty much anything until my bipolar condition became a danger to me and others. Not my family, so don't go there.
 Now to the point. The last thing I expected was for it to shoot my libido through the roof. I've been married for almost 30yrs and having 3 girls in the house put a real damper on our sex life. I've been completely stable for quite some time now and our marriage is like it was in the beginning. Best side effect ever! 
 Now for the question.  Has anyone else had a similar experience? I'm hoping this side effect (libido) is a permanent state. Does anyone have any input?
