Agree with my colleagues. Needs to be seen. Relaxation exercises, meditation, don't worry

Eat non spicy food . Seek online consultation

Stop eating spicy foods,eat more times with less amount of food get sleep study with consultation

Agree with opinion. In addition take Pan-D one tab on empty stomach.you have  to maintain good sleep hygiene.That means don't take nap in afternoon. Stick to a time schedule when to sleep. Don't think that you r not getting sleep, it creates anxiety and will interfere in onset of sleep. Also do some physical activity and read  something before u sleep
