1- I've lost count. A lot.

2- This depends on the person. The nose pinch RC and sticking my finger through my palm work best for me, but everyone is different.

3- I do a reality check anytime I see something surreal, or any time dreaming crosses my mind. This could be hours apart or just several minutes, it doesn't really matter. Sometimes it helps to do multiple reality checks at once, though, as Dying_Dignity said.
