Has anyone tried fast-acting lithium before? I’m currently on 1500 mg extended release (ER) taken all at night and I want to switch. I can’t handle the tremor/morning brain fog anymore. My blood level is still 0.7-0.8, and I’m also better than I ever have been mentally.

Do you find you are less brain foggy and/or tremor-y (less side effects in general) on fast acting?

Thanks!
