depression
"I have unipolar depression with occasional manic symptoms.  For 20 years I was on antidepressants but started Quetiapine about 6 months ago in conjunction with Citalopram.  When I reached a daily dose of 300mg I was feeling great mentally.  But the side effects of constipation and tiredness made it difficult to stay on this medication long-term so I'll be trying lamotrigine next."
