When do you know your manic episode is over?

Hello, I ended up in a manic episode a week and half ago. My therapist confirmed it after he heard of my active symptoms of the time. I'm medicated for my Bipolar, so my manic symptoms were less severe. How do you know when your manic episode is over? I originally thought it ended when I stayed up for multiple days and then one day I was super tired and slept all day. However I still feel like I can't slow down and everything is moving too fast. I have too much energy and I feel like I have to keep doing stuff and wanting to socialize constantly. I apologize that this post is so random and I'm wondering if this just sounds like anxiety, however I haven't had a manic episode since last year and lack memory there. What are your personal signs when it's over?
