Hello Welcome to HCM. Change in environment can affect sleeping schedule. I suppose this is the reason for your disturbed sleep. Here are some suggestions which might prove helpful for you: 1. Take sleep inducing medicine like zolpidem 5mg when required. 2. The ambience of your room should be pleasant. The room should be tidy and quiet. 3. Avoid tea, coffee and chocolates at bedtime. 4. Donot take heavy meals in dinner. 5. Take a warm water bath before going to bed. 6. Donot listen to loud music at bed. 7. Dont force yourself to sleep. If you are unable to sleep within 20minutes of lying on bed, leave the bed and take light walk in your balcony. Hope this helps you. Thanks.
