Just wondering if any one has experience of the antidepressant Mirtazapine. Dad has recently started on 30 mg daily. It says it can cause drowsiness at first but Dad is sleeping about 22 hours a day. I know it could be his other illness but wondered if anyone had had this problem when taking the drug. If so, does it ease after the first few weeks? I'm going to contact his Cpn after the weekend but thought I'd try here first. Zan
