Hi I am a software engineer and varying sleeping patterns is a part f my career as the work that I do requires me to be awake for long time in the night to finish my deadlines. For about 4 years into the profession I had no problems but in the recent times I have developed the problem of irregular sleeping patterns. Then I thought that I would be able to return to normal sleeping pattern on my own but it wasnít to be. I couldnít return to my regular sleeping pattern. Then I tried out several pills but nothing worked for me. Then I was wondering what to do. Then I consulted a doctor who advised me to use my lunesta a medicine that would help me to get out of my problems. I tried it out and it actually solved my problems. I am very happy for using this medicine. It has helped me to come back to my original life pattern.
