I don't know but I totally relate. I make all kinds if different markings and notes on my mood chart rather than just a check. Just for me to remember somehow. At times i have just kept running notes like

10/3 pm
off, clingy feeling. jagged edges. hate it. want to drink.

10/4 am
had a blip of feeling really awesome and connected and happy but now just exhausted and super sensitive.

etc something like that. it helps me track over time and in an episode. the notes help me remember much more what exactly i was feeling. Also it is nice to express my crappy feelings

But i feel a lot of the time like I am not "up" or "down" but still not "baseline". It is way more complicated than that. So I try to find different ways to describe it for myself. words I have used are "off", "weird", "jagged", "raw", "tilting", "spiraling", etc etc etc and when all else fails I just tell my husband I am feeling all Bipolar.
