I have inappropriate laughter much more than the crying. I hate it. It's extremely humiliating. Even my own family took a long time to really believe and understand that I was not feeling any amusement and was simply a prisoner watching in silent horror from inside my head as my body forced me to laugh like a crazy person. The worst is that I can't make it stop. Sometimes it goes on so long that I can't catch my breath and feel like I'm going to pass out.
Nuedexta helps a lot but doesn't completely get rid of it for me. I am lucky in that I only have a $30/month copay for it.
