What Could Be The Best Medication For Depression, Increasing The Lithium Causing Depression And Trilaphon Has Side Effects?

I am a 57 year old female with Bipolar 2 A few months ago my meds were lower because I was falling asleep as soon as I sat down even in conversation. I take Wellbutrin Lithium , Loranzapam, Serquel,andDepoqote and neurotin for migraines and more. Now 4 to 6 months later my lithhuim is450mg, Serquel 150 loranzapam is still at .5mg and has been for years, anyway my depression is too much and my doctor said raise lithium I said no because of double vision which went away when it was lowered. So he said up the serequel to 300mg or take Mirtazapine 30mg. I like d trilaphon which was changed to





I erased it all. I am a 57 year old female with bipolar 2. I have been on Lithium ER 450mg at night which has been recently lowered from 1 at night, and one half in the morning.Wellbutrin 300mg,Ativan .5mg, Divalproex ER 500mg, Serquel was lowered from 300 to 150mg , Neurontin 800mg 3x a day. The lithium and serquel were lowered about 4 to6 months ago because I was falling asleep as soon as I sat down and even in conversations. I was also dealing with sleep apnea. Now I am too depressed and quick to anger and my psychiatrist wants to up my serquel to 300mg or to start Mirtazapine 30mg, I do not want to up my lithium due to in causes me to have double vision. I am scared of the Mirtazapine and feel like the serquel is better because it is an antipsychtic. I did really well on trilaphone but was switched to srequel because of side affects long lasting. Dr. left it up to me.
