I belive on medicines like i eat revital h because i think there is no energy my body producing sometimes i take nitress to take a sleep but now these medication also not working at me . Not getting sound sleep even i sleep for 11 hours also daily routine is not up to mark always feels sleepy at work also , gaining weight day by day. I use to speak unknown , meaningless words not known which language at night when i feel depressed or any tension of work or monetary issues
