As someone undergoing Hepatitis B treatment, I've been experiencing insomnia and fatigue while taking Entecavir. To manage these side effects, I've been focusing on improving my sleep hygiene by maintaining a consistent sleep schedule and creating a relaxing bedtime routine. I've also found that limiting caffeine and screen time before bed has helped me fall asleep more easily. In addition, incorporating daily exercise and relaxation techniques like meditation and deep breathing exercises have contributed to easing my fatigue. It's important to remember that everyone's experience is different, so it's crucial to consult with your healthcare provider before making any changes to your daily routine.
