Hi, Ali:<br /><br /><br />I have uploaded your edited document, and I hope that you find the suggestions helpful. If you have any questions, please send a message to me via Editor World.<br /><br />I apologize for the extensive red markup, but I wanted to create "a coherent and cohesive introduction" as you requested. I think we have it. This is shaping up to be an excellent study of hypnotic-drugs&nbsp;prescribing and I wish you well. You've certainly put a lot of work into it thus far.<br /><br />Best wishes - George<br /><br />I am usually available for editing between 6:00 am and 10:30 pm (EST). If my status says 'unavailable', you can still reach me via Editor World.<br /><br />
