My husband has anxiety every evening and I give him 15mg mirtazapine when he goes to bed. He may drop off to sleep once settled but often wakes in the night. GP suggested half tablet of 1mg lorazepam. Very difficult to break tab in half & mixed success. Notice he talks incessantly & may get out of bed looking for shoes and wanders round house, then shouts for me as he’s lost. He’s very groggy the next morning after taking lorazepam and I’m not sure it’s the best choice for him. I’m getting very little sleep. Any advice on medication?
