Insomnia for the past 3 months can happen due to stress, anxiety, irregular sleep habits, excessive screen time, depression, caffeine intake, or sometimes medical conditions and medicines. Since your Hypothyroidism is under control and you are taking Thyronorm 150 regularly, it is still important to make sure your thyroid levels remain properly balanced, because both low and high thyroid hormone levels can affect sleep. Libotryp DS may not work equally well for everyone, and you should avoid increasing or changing the dose on your own without medical advice. Along with medicines, improving sleep habits is very important. Try to sleep and wake up at the same time every day, avoid mobile phones and television for at least 1 hour before bedtime, reduce tea, coffee, nicotine, and heavy meals in the evening, and keep your bedroom quiet and comfortable. Gentle exercise, meditation, deep breathing, and stress management may also improve sleep naturally over time. Avoid sleeping during the daytime if possible. If poor sleep is linked to anxiety, overthinking, or low mood, treating the underlying stress can help significantly. Since your insomnia has continued for several months despite medication, it would be best to consult a physician or psychiatrist for proper evaluation. The doctor may review your medicines, check thyroid reports if needed, and suggest safer long-term treatment options or counselling techniques that can improve sleep quality without depending only on sleeping tablets. Seek medical advice promptly if you also experience severe anxiety, depression, panic attacks, or daytime functioning problems due to lack of sleep.
