Normal emotions are going to happen, you can and will get happy and sad you might sleep more or less here and there. That said..... Meds wont always keep your from an episode of course.

If you notice you tossing and turning and it continues you certainly need to be pro active.. Increase self care and sleep hygiene if that doesnt help then contact your Pdoc sooner rather than later.. This time varies for people. It just depends on your own tolerance for lack of sleep. Some people can go a few weeks with wonky sleep and be okay and some people cant go more than a few days... I would say see where you are on the spectrum.

I hope your good sleeping returns
