Create a routine: Create a routine that you practice every day around that time -- something that occupies you and you also enjoy. It could be preparing a nice meal, or listening to music, or physically exercising, etc. You can also do breathing exercises. Here's a link to dr. Andrew weil explaining & demonstrating this: http://www.Drweil.Com/drw/u/vdr00112/the-4-7-8-breath-benefits-and-demonstration.Html.
