I dont have a diagnosis of bipolar but from time to time I feel the same,
nightime is a particular worry as I will have all sorts of weird urges,
anything from wanting to bounce on bed at 3am in the morning,
to wanting to paint windows,
going walkabout in the wee hours,
doing the gardening in the wee hours,
feeling elated and hyper,not needing sleep,
the list goes on and on,
at best it will last 2 or 3 days then I crash horribly.
