How concerned do you feel about this? If you really analyze yourself right now, are there any symptoms you see that tend to show up right before mania? How quickly do you tend to escalate?
I mean, honestly if I didn't sleep well one night I'd give it another night and see if I still felt I didn't need the sleep before reaching out (I usually have sleeping issues and my manias take up to a week before things become any sort of real problem), but if I chatted with someone from my team I would definitely mention it, or if you have other concerning symptoms or spiral quickly it'd be good to reach out.
