Sounds more mixed or dysphoric mania perhaps. I have dysphoric mania and mixed episodes and I'm an ultradian cycler. Fun. So, I often can't tell what my mood is exactly. Over time and tracking for the past 4 years I've figured out my pattner. I'm pretty much always mixed (yes, that is a thing, actually I discovered.) I don't have "normal" phases. I'm either more depressed or more manic, but always both. My mania isn't has high so it appears more like hypomania, but that's because I'm always depressed at the same time.

Very complicated.

Also, I do very well at 300 mg of lithium. I do not as good at 600 mg and I go into some crazy freak out mode at 1200 mg. I shake like you wouldn't believe and it elevates my racing thoughts. 300 mg is the key for me. I'm very sensitive to meds of all types. So, I know there are guidelines or whatever, but really, I think it is much more complicated than a text book but good luck finding a doctor who gets that.
