Hi everyone

This is is my first time posting.
I hope everyone is doing well.
Has anyone ever dealt with uncontrollable laughter.

I have recently been struggling to get my son to stop this behavior.
He Only calms down when is on clonidine. When the medication wears off he can go on and on.

Does anyone know of any natural medication, or supplements that can help keep him calm when is not on clonidine.?
Any advice is greatly appreciated.
