Hello
I am a 53 yr old woman
I have been physically healthy most of my life with exception of battling my mental illness bi polar 2 Sunce June of last summer I have been on three different mood stabilizers for my bipolar depression As of Nov 15 I started lithium 900 mg. I am exhausted everyday my mood has lifted but my body is not ? What in the heck is going on ? If my mood is improved why isn't my body back to normal?
I am on Celexa 40 mg Wellbutrin 20 mg 900 mg of lithium in the morning. it disturbs my sleep taking lithium at night and adderall X 30 mg three times a day. I'm trying to be compliant and drink much water etc I do not understand why I am exhausted and so irritated I want my life back it has been a long six months. I brush my teeth and go to bed I take a shower I want to lay down I've been pushing myself to walk daily I have a healthy lifestyle I'm still menstueating every 27 days I eat a diet of leafy veggies once in a while red wine yogurt lean meats and yogurts and probiotics and multivitamins
