Hi sir, this is Gökhan from Turkey. Actually, i have no problem of my slepping. But i want to reduce my sleepping time. Because, i am very busy these, so i can t finish my business during a day. Generally i sleep a day for 6 hour. But, i want to reduce this time as 4 hours. So for that what can i do. What could you suggest me about it. Thank You very much. Wishing you the very best of business.
