Golden Sunrise Rakhi ma'am.
Thank you so much for guiding. I was in a very desperate state of mind as things were getting out of hands.
Its true, medicines given were the reason. They finally had to give him tablet to sleep. As he had started hallucinating and talking senseless. All i could do was ask VK to "please help".
I will check the tip. I have to first calm myself down. Thank you for your wishes.
