Needs further evaluation of sleep

Hi, I appreciate that you reached out with your concern. It’s great to hear that your anxiety has been under control since stopping medication. Sleep issues can sometimes persist even after anxiety symptoms fade, and your upcoming exams could be unconsciously affecting your sleep, even if you don’t feel anxious. Try improving sleep hygiene: maintain a fixed sleep schedule, limit screen time before bed, avoid caffeine in the evening, and practice relaxation techniques like deep breathing or meditation, progressive muscle relaxation. You may seek therapy and considering techniques like Cognitive Behavioral Therapy (CBT).

Taking Lorazepam isn't a good option rather you can use melatonin tablets which are good fir stabilizing tge circadian rhythm.

Hi.. lack of sleep can be one of the presentations of anxiety. Maybe you can continue escitalopram till exams are completed.
