I haven’t been taking my lithium like I’ve been supposed to. I oversleep then it’s too late to take it. I’ve been weak, lost my appetite, headaches, body aches, chest feel funny, etc. I tested negative for both Covid and flu. So no it’s not that. My symptoms are worse at night with added hand and foot numbness and tight throat and heart races. Could it be my lithium? I’m supposed to take 600 mg a day. But I’ve Been forgetting. Help please.
