Hi I am feeling dizzy and drowsy from. Last two three days. I work on computer in office. whenever I sit in front of pc. I start to feel drowsy. I was feeling dehydrated and tired drowsy dizzy all the time. Even at home also. What could be the reason. 2 days back I noticed my mouth gets dry. I drink lots of water bit still sleeping. I have had to make extreme efforts to keep my eyes open at works. They automatically shuts and I keep yawning inspite of good sleep. I lost weight 2 kgs recently. Is it eye problem or any other issue. My eyes feel too heavy and sleepy. Sometimes I feel spinning around head while sitting talking and walking. Kindly suggest. What is the reason. This is happening from last 5.6 days.
