So I'm on day 6 of 300 mg lithium and the effects have been strange. I have become extremely tense and stressed all the time, even if there is nothing to stress about. My mind feels like its been drained dry of its energy, nothing is enjoyable and concentration is difficult, but physically I can still get up and do things without trouble and don't feel particularly tired. I have an old prescription of Vyvanse that I got for ADHD that I wasn't taking because it caused hypomania but now I have to take it daily just to make it through the day, it eases the stress and allows me to focus a little bit. My emotions feel blunted, not numb necessarily, just like they're being smothered under a blanket. My anxiety is gone, which is nice, but theres still this constant uneasiness, like things just seem off. Even though I don't feel hypomanic anymore I'm still only getting 6 hours of sleep max, I can fall asleep fine but then I wake up and can't fall back asleep. I've also started to notice some memory issues and muscle tightness.

Has anyone had anything like this? I know it takes a while to adjust but the constant headaches and stress is getting tough to manage and I can't imagine going for a month like this. Does this stuff go away?
