Less sleep can be a sign of heading into a hypo/mania .. But not 100% .. Everyone is different . Just keep an eye on your moods .. Start charting them if you dont already .. Can be done on paper or there are apps for you phone ..If you see a pattern of less sleep and increasing activity beyond your normal Then is the time to be concerned .

Just do a self check daily .. ( just note how your feeling) and go about your day.

Do you have someone that is close to you that can toss up a flag if you seem to go too high ?
